However, electrical energy does not travel though the wire as sound travels through air but instead always travels in the space outside of the wires. … Current is a matter-flow, not an energy flow.

How electricity is conducted through a wire?


How fast does electricity travel through wire?

In the case of an electrical cord connecting a table lamp or some other household item to a power source, the copper wire inside the cord acts as the conductor. This energy travels as electromagnetic waves at about the speed of light, which is 670,616,629 miles per hour,1 or 300 million meters per second.
