What is the symbol used to represent alternating current?

1 Answer

The symbol used to represent alternating current (AC) is a sine wave. It's a graphical representation of how the voltage or current in an AC circuit varies over time. The waveform of the sine wave symbolizes the regular and smooth oscillation of the direction or magnitude of the current or voltage, which is a characteristic feature of AC. The wave alternates between positive and negative values, representing the changing direction of the current flow in the circuit.
