AC Voltage Waveform

A voltage that changes direction and magnitude over time in a repeating pattern, like a sine wave.

AC Voltage Source Symbol

A graphic representation of an alternating current voltage source. It typically includes a lowercase e (lower case e) to indicate time-varying voltage.

AC Current

Electric current that reverses direction in a regular pattern.

Sinusoidal Waveform

A repeating, wave-like pattern often representing AC voltage or current, with a smooth curve.
