When conduction electrons pass through a device with resista

When conduction electrons pass through a device with resistance, which describes their energy? Their potential energy increases. Their kinetic energy increases. Their potential energy decreases. Their kinetic energy decreases.

Solution

If the conductions electrons pass through the solid device with resistance

, its average kinetic energy is constant and moves with constant drift

Speed. In this case the conduction electrons lost their potential energy

and the lost of potential energy converted into heat . so the potential

energy decreases when they move a device with resistance.
