AC circuits, or alternating current circuits, are electrical circuits in which the direction of current periodically reverses. This means that the flow of electrons alternates back and forth in a regular pattern.

Frequency: The frequency of an AC circuit refers to how many complete cycles or oscillations occur per second. It is measured in hertz (Hz).
Amplitude: The amplitude of an AC circuit represents the maximum value or strength of the alternating current. It indicates how far the electrons move from their equilibrium position.
Phase Difference: Phase difference refers to the time delay between two waves or signals in an AC circuit. It measures how much one wave is shifted compared to another wave.
