Wires are made from materials that carry, or conduct, electrons more easily than other materials. Materials that conduct electrons easily are called conductors. … When current passes through the wires inside the bulb, electrical energy changes into heat energy and light energy.
Electrical energy also travels via compression waves, with the waves travelling through the electrons within the wire. 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.
