Dear all
i've thinking, how can a circuit have a steady current?
the reason for this seemingly naiive question is:
if I is contant it means the velocity at which the charges move is constant. But if the velocity is contant that means their KE is constant. So in a circuit with a resister for example, how can electrons before the resistor have the same velocity as the ones coming out of it? doesn't that mean they haven't lost any energy?
Please enlighten me...
