Answer 1

Answer:

here medium's material means the rubber coating on the wires.

Explanation:

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. Add to this, if the wires are single stranded, broken or twisted, the resistance of the medium increases even further.
