When conduction electrons pass through a device with resistance, which describes their energy?

a) their potential energy increases.

b) their kinetic energy increases

c) their potential energy decreases

d) their kinetic energy decreases

a) their potential energy increases.

Explanation:

Ohm's Law is

R= V/I

Where R= Resistance

V= potential difference or potential energy

I= current or conduction electron flow rate

Clearly R and V are directly proportional i-e Potential energy increases with resistance.
