Where Can I Find 40 Gauge Copper Wire? 1

1. There is a copper wire attached to my old light switch, do I need it?

If you have metal conduit in the wall as a cable route then the ground wire fixes to that, if it's plastic then the switch holder will contain a little socket for the wire to keep it out of the way, put a sleeve over the wire before fixing it in place. You could attach it to a holding screw for the box instead

2. Which (mesh size) copper wire mesh do you recommend for this?

Paranoia? Why are so many people so stupid?

3. Coiled copper wire around 15a power cable for AC

What you have there is basically a transformer. There would have to be some voltage induced in the copper conductor, but across only a couple turns of the paracord (the width of an infant's mouth) the voltage would have to be quite minimal because 1) the paracord is wrapped around both hot and neutral so the magnetic field will be near zero and 2) the distance between the paracord and the conductors in the power cord is relatively large. There does not appear to be an increase of risk of fire or damage to the power cable on account of the paracord being wound around it. Unless the infant makes quite a routine of it or bites very hard, I would guess he's unlikely to pierce the insulation on the power cord anyway.You could consider treating the cord in some other way if you desired:

4. How is the loop law applicable when I connect a battery with an ideal copper wire?

There would be a potential drop. If the wire has literally $0$ resistance, then this is a nonphysical question and no physical answer can be provided. Energy will be lost due to heat in the wire. The current will will be very high, as $I=fracVR$ and $R$ is very low, and the power dissipated (heat) will be very high, as $P=IV$.

5. Is insulated copper wire required?

This depends on what you mean by "insulated". In a motor or any device that uses multiple turns to form an inductor - a device that increases the magnetic field by using a single isolated multi-turn conductor, then the current MUST flow into the wire at the input, travel through the length of the wire without any alternative paths available and exit at the other end. Both wire in 1. and 2. are potentially suited for constructing motors. The aim is to use a wire with as mechanically thin as coating as possible BUT having a voltage breakdown rating adequate for the task and adequate resistance to mechanical damage which could occur during manufacture and use. Wire of type 2. with thick insulation is usually used for distribution and interconnection purposes, where resistance to mechanical stress is of great importance.Wire of type 1. is normally used in motors where voltage resistance is paramount and mechanical issues are controlled when the wire is handled and wound and in the final product.

6. Coil about 30 turns of a thin copper wire around a glass tank (like the ones used for aquariums) and connect t

Why do not you do that, tell us what the pattern is, then ask us to help you explain it. Notice that I said *help* you explain it, not would o your homework for you.'

7. How to clean a copper wire? The simplest method possible.?

i use an eraser from a pencil

8. how much money is it to sell Copper Wire?

Make sure its pure copper, also it varies from where you sell it my dad sells it to some guy who buys from home so you might want to ask around.PS you want to have PURE copper and you will make a lot of money because copper is high now

9. how would i make simple phone from copper wire?

Wire, wraps aound magnet, magnet glued to paper. (ie a speaker), conect this to the phone line and you would probable hear something

10. I connected two ends of battery with copper wire, and nothing happened. Why? [closed]

1.5v is not enough to "electrocute" you. In fact, it may not even be enough to make a visible spark when you short the battery. (Shorting a battery is, by the way, a Bad Idea. There's a chance of leakage, overheating, all the bad stuff. )If the battery and the wire did not get warm during the short, the battery probably was not any good to begin with. Even a AA should change noticeably. Maybe there's something wrong with your motor construction? Weak magnets? There are a lot of improvised motor designs. Post a link to the one you are using and maybe some hypotheses can be raised.

Is It Safe to Ground an Inverter and/or Individual Loads in a House on Wheels, and If so, How?
Ground -electrically - does not mean what the word implies.For purpose of your question, the house can be rolling or parked. In either case, the "ground" system has two separate parts:all the copper wires downstream of the panel (third wire in every circuit) - those wires are always the same, parked or in motion, they are wired and always remain undisturbed,the copper wire upstream of the panel (usually one thick wire), normally from the panel to the ground rod(s). That wire connection depends on the particulars, either a ground rod, and/or perhaps the house/vehicle structural metal, and in turn it may need to go to the inverter.; this last connection should be dictated by the inverteru2019s instruction. Iu2019d be quite careful with that. The inverter may be effectively tied to both the vehicleu2019s DC system and the AC system, the two may share a common point, DC neg and AC neutral, or not. Again see instructions.P.s.: Individual loads (in the question) should never be "grounded" by adding wires, the applianceu2019s third pin does that and - if ever needed - works via item (1), above.One consideration, if the inverter puts out a "clean" sinusoid (not all do), is to use GFCI in the first receptacle of every circuit. In a pinch, make/buy a short portable GFCI extension. Look to see if the inverter may already incorporate GFCI protection.GFCI are a really - really - good idea; especially anywhere near water, or where cables are more likely to became frayed..• Related QuestionsHow often have you worn a paper mask when working out?I have worn a face mask every day during my twice-daily 4 mile bicycle ride, since the first week of April, 2020. Until the first week of July, this was a DIY mask made from rubber bands, staples, and a blue paper shop towel, instructions here:As an aside, though I was willing to rely on this mask only for supplemental protection in a low risk suburban environment, subsequent lab studies have found a single layer of these shop towels trap 87% of nanoparticles. That means a slightly different design using two layers will trap 98% as compared to 99% for a standard surgical mask.Since July, Iu2019ve been able to use sugical masks, though I have questioned whether masks of such quality are actually better. The surgical masks I was able to buy only are or the cheaper variety, which are not obviously multi-layer like the masks I realized I was out of at the start of the pandemic. Still, they are made of non-woven polymer fabric, and to are almost certainly better than the single layer shop towel mask.Here are my observations:The shop towel mask is more comfortable slightly larger, and better fits my large male face.With a paper clip opened up and taped inside as a bridge clip, the shop towel mask seals to by face slightly better than the commercial mask.The shop towel is a bit floppy, and I ended up embedding a copper wire into my masks for added support during the huffing and puffing of exercise.Even so, either mask tends to get sucked against the nose, reducing ventilation during heavy exertion, and in practice I solve this with both masks by breathing through my mouth.The paper mask starts to grow damp near the end of a four mile ride in humid Texas, where sweat mostly pours down the face. The commercial mask is made of plastic fiber, and wicks any moisture up without noticeable affect.I started out changing the paper mask every week, but ended up using the last one for almost two months, till the bridge clip (held in my medical tape) fell out. The commercial mask should easily last two monthsu2014though I should probably alternate masks. Paper is known to degrade virus particles within 24 hours; the polymers from which the commercial mask is made probably donu2019t, so a three day rotation would be safer.Neither mask affects respiration in the slightest during my ride. This is partly because forward motion is enough to slightly ventilate the mask, but mostly just because Iu2019m breathing harder and deeper, so dead air trapped in the mask is diluted into larger lungfuls.Either mask, but especially the commercial mask, do somewhat interfere with the oxygen supply / CO2 clearance when taking a casual walk and chatting. This is because when walking in the heat, you use more oxygen, but when chatting, you tend to breath more slowly and in shallower breaths, so the dead air in the mask has a larger proportional effect. The solution is simply to remember to take a full breath while your partner is talking. Itu2019s not a problem.How often have you worn a paper mask when working out?.------I have two pieces of rusty barbed wire about 7 inches long, they were used in the Brusilov offensive during WWI, how do I preserve them to stop any further deterioration?If the only purpose were to preserve metallurgical integrity, I would agree that you should clean off the rust, and heavily paint or coat the artifacts to prevent further oxidation.However, in this case, the items are valued because of their historical association. I might thus consider insteadu2026Remove any obviously loose or flaking rust, since this will fall off anyway,Carefully clean the wire with warm soapy water, being careful to wear latex or neoprene gloves to prevent skin oils or salt from being deposited on them,Rinse repeatedly with distilled water (to avoid electrolytes contaminating the surface. Then dry thoroughly with a hair dryer or under a lamp etc. (But do not heat to high temperature as in an oven or with a flame, as that will promote further oxidation.Finally, now that they are thoroughly clean and completely dryu2026 spray or dip them with a coating of clear laquer. Let it dry, and then repeat. Then store them in a display case or other container where they will not be exposed to excess humidity etc.This treatment, or similar, will preserve not only the underlying metal, but also the "appearance" of it. People will look at it and believe that it is what you're claiming it to be. Otherwise, if you paint it, or plate it with copper or gold, etc., then it won't look anything like what it looked like in WW I.In History, "context" is very nearly everything. Some of the sand in my shoe right now may have once been in Egypt, under the feet of Ramses or Moses. But nobody buys tickets to see my shoes.I have two pieces of rusty barbed wire about 7 inches long, they were used in the Brusilov offensive during WWI, how do I preserve them to stop any further deterioration?------What should I know about SMD diodes before looking to buy some?SMD can mean surface mount device.. but it is also a size of one kind of surface mount devicesu2026 range SMA,SMB,SMC,SMD where D is the largest.The problem with small case size diodes is that they can get hot. The silicon diode drops .6v to 1.2 volts and sometimes are used with currents that pretty high at peaks.. like in switching regulators. They can need a large heat-pad of copper near the lead to soak up the heat.If you are hand soldering, there are other form factors like diodes (1n914/1n4148/1n400x) which are normally axial leads, but without the leads. Really easy to hand solder onto a surface mount style PCB. There are also wing-leads that are much easier to solder than J leads or .. no leadsu2026The diodes are about the most rugged when it comes to soldering.. never have to worry about using a 40 watt, .015 inch soldering tip. They are also one of the best at static discharge nearby, not direct. Like BJT (2n440x) transistors, they are relatively immune to handling without the need for u2018groundingu2019 wires or sheets.Now, if you are using schottky diodes then this is not all true. I use schottky diodes in place of any normal diode, and I pick ones with 0.12 to .25 volt drop at computer current levels. They are expensive, but you will never kill a computer input with these babies to VCC and GND. Of course there are units dedicated to static discharge.. basically diodes with high joule capacity and very low leakage.You should also know that a Mosfet with low gate turn-on volts and a low milliohm source-drain resistance when onu2026 Is the almost ideal diode. Done right, the forward voltage drop is insignificant. I use these to make full wave rectifiers with about 10 mv lossu2026. so that the battery powering my device can be inserted any which way. (Beware that Mosfets are notorious for hating static.)What should I know about SMD diodes before looking to buy some?
