Answer 2

Answer:

The reason for why wires heat up when a current flows through them is that a battery converts chemical energy into electric potential energy. ... This thermal energy causes the wire to heat up. Electrical burns occur when you hold on to a wire, and due to heat transfer, some of this thermal energy is transferred to you.
