Energy and Electric power.

Power is the speed at which work is done.

Electric power is the multiplication of the current (amps) by the voltage (volts). P = I x V.

Step Response of RL Circuits When a constant voltage is suddenly applied to an RL circuit, an increasing a current goes through the conductor and creates a magnetic field that expands with the increasing current. This current will reach a maximum value, and the magnetic field stop expanding. The expanding magnetic field induces a Counter-Electromotive Force […]
