How does the current remain the same in a circuit?

How does an AC circuit get anything done?

Stumped on understanding a Feynman lecture about force from wire on magnet

From where do electrons gain kinetic energy through a circuit?

How do resistors generate different heat if we make the current fixed and changed the voltage and resistance? Notice the flow of charge is constant

Watts vs. volts amperes

What *exactly* is electrical current, voltage, and resistance?

Does Ohm's law $V = IR$ mean voltage causes current, or does it just say that voltage and current are related?

When the voltage is increased does the speed of electrons increase or does the electron density increase?

In aluminum, how does electricity travel through the surface oxide layer?
