Question

what causes heat and light in a wire

Answer 1

ᴀɴsᴡᴇʀ :

The Electrical Current Running Through the Wiring

The electrical current through the wires itself causes the home wiring to heat up. This is because as the electrons flow they come across the resistive forces of the medium's material, releasing energy that is expended in the form of heat energy.
