A metal wire connecting the terminals of a battery with potential difference V bat gets warm as

Question:

A metal wire connecting the terminals of a battery with potential difference ΔV_bat gets warm as it draws a current I.

a. What is ΔU, the change in potential energy of charge Q as it passes through the wire?

b. Where does this energy go?

c. Power is the rate of transfer of energy. Based on your answer to part a, find an expression for the power supplied by the battery to warm the wire.

d. What power does a 1.5 V battery supply to a wire drawing a 1.2 A current?
