WebMar 25, 2024 · The resistance of a nichrome wire is (roughly) 100 times higher than that of a wire the same size made from copper (an excellent conductor), but only a quarter as much as a similar-sized graphite rod (a fairly good conductor) and maybe only a million trillionth that of a really good insulator such as glass. The numbers speak for themselves ... WebWire gauge - The wire gauge, or size of the wire, also determines how much resistance the wire has. The larger the wire, the less resistance. The smaller the gauge, the larger the wire -- so a 16-gauge wire is bigger than a 24-gauge wire. Wire gauges go all the way down to zero, which is also called 1/0 (one aught).

Because the current is squared in the equation, two amperes through the same wire would heat it at a rate of 4 watts, and so on. Example. smart cc

"WebJun 28, 2024 · Configure the multimeter to measure resistance. There are three configuration steps: Put the black probe in the socket labeled “COM” for “common,” meaning it’s common to all measurements. Once it’s there, it’ll never need to be moved. Put the red probe in the socket labeled with the Greek Omega symbol (Ω) for resistance. " - How much resistance in a wire
