# How much length do you lose when twisting wire?

According to my own twisting square wire experiences, a single strand of wire from 20 to lesser gauges will not lose enough length to be concerned about. Twisting bigger gauges from 19 to 16 results in a loss of around 1/16 to 1/8 inch, whilst 14 and 12 gauges lose approximately 1/4 inch.

This is because the average human hair is around 75 microns wide, and for an ideal circle you need exactly as many hairs as there are inches around your head. So if you have a head size of 50 inches, then you need around 20 million hairs for your wig. Each one of those hairs can be twisted up to 100 times its original length, so by the end of your journey you're looking at 20 million inches or 2.5 miles of wire! Even if only half of them remain after being used, that's more than enough to cover most people's heads.

The other factor to take into account is how thick your wires need to be. The thicker they are the longer they will last. At least three strands of thin wire will always fail before any thickness of four or more. But even so, 20 million inches is less than 1 yard, which is the usual maximum length for a wig fabric. And since each hair needs to be separated by at least 24 inches, the actual amount of material used is much less than this.

In conclusion, losing length when twisting wire is irrelevant when using grades of 20 or less.

## Does it matter what wire you use?

Regrettably, size does matter. The simplest basic reason for why wire gauge matters is that the thinner a wire is (the higher the gauge), the greater the resistance to current passage. So, for example, 17AWG wire has almost twice as much copper per foot as 20AWG wire. And because resistance increases with the fourth power of current, this means that 17AWG wire requires half as much electricity to heat up as 20AWG wire.

But there are other reasons why you might want to choose particular wires for your projects. For example: if you need to connect several small wires together, using smaller ones will reduce the risk of an electrical short circuit. Or if you plan to put your project outside, it may be better to use something less thick or more flexible than solid metal wire.

Finally, some things in electronics work best when they're done right, and others work better if they're done wrong. For example: if you connect one side of a battery to a light bulb then the light bulb will glow even without any current being passed through it. This is because current is flowing into one end of the battery, down through the wiring, to the lamp, and back out the other end. There's no need for the battery to actually charge up at this point - it's like putting oil in your car's engine block - but later on, when you drive home, the battery will be full of energy thanks to this little experiment.

## How much weight can a 14-gauge wire hold?

A 14 gauge high tensile wire strand will break at 800 lbs. , giving you a 1,600 lb. Breaking strength in barbed wire with only 1.5–2 percent stretching. It is very strong but also very brittle.

Barbed wire was originally made from steel wires that were twisted or bundled together then coated with some kind of corrosive material like zinc or iron to prevent animals and people who did not own land from trespassing on it. The wires were later replaced with aluminum wire but they are now used instead. Barbed wire is used to create a barrier between two areas, either physically (such as a fence) or legally (such as a game preserve). It is often used to keep animals away from certain areas of land or to prevent them from entering others.

The strength of barbed wire is based on the number of sharp points on each strand. The more points, the stronger the wire. Also, heavier gauges have greater strength than thinner ones. However, there is a limit to how much the thickness of the wire can be reduced without losing strength. For example, a 7-gauge wire will still have about 750 pounds per square inch (psi) breaking strength while a 4-gauge wire will only have 200 psi strength.
