Copper and aluminum used for electric wires
Copper
Electric current in a metal conductor is carried by a wire. This wire has been specifically adapted to carry this current.
copper plated aluminum wire
An electrode
the metal casing of the electric kettle
In most cases, copper is the metal used in wire.
A fuse.
Yes, because to conduct electricity you need a metal wire, (usually copper). However they have a plastic outer coating (sheath) which protects them and insulates them.
normally 8 gauge wire is used for electric heat furnaces.
A fuse is a thin metal wire that is designed to melt when the electric current is too large, breaking the circuit and preventing damage to other components.
In a metal wire electrons go and go and go! when conducting electric current.
Because it is a great conductor of electric and cheaper then platinum or Gold or Silver which are much better conductors to cost prohibitive
