A wire is made out of thin, easy to bend metel and rubber so you don't electricute you're self (at least I think).
copper?
All electric currents create magnetic fields. If you wind wire into a coil and pass current through the wire, that is an electromagnet.
who invented electric wire
Because then it wouldn't 'blow' at the prescribed amperage. -A fuse is made with very fine tolerance wire to melt at an EXACT amperage.
The thin wire inside an electric bulb is called a filament. It is usually made of tungsten and becomes hot and emits light when an electric current passes through it.
Electric current is made to flow in a wire by applying a presure of extra electrons at one end of the wire .. this excites the atoms in the wire and that excitement is transfered to the other end of the wire along the way the excitement is displayed as light, heat, or magnetism used to turn motors
Electromagnet.
increase
It's resistance to electric current increases.
It's resistance to electric current increases.
Electromagnets.
If wire delivering a certain amount of current is made narrower, the resistance of the wire will increase. This will limit current, and the wire will warm up some. If the wire is made shorter, resistance will decrease. The electrical codes have well published limits on the amount of current different types of wire can carry.
