AC Voltage Symbol - Electrical Circuit Diagram Icon #1498797 (License: Personal Use)

This icon represents an AC (alternating current) voltage source in electrical schematics, where the sine wave denotes the periodic reversal of polarity over time. The circular enclosure with horizontal input/output lines signifies a two-terminal component, commonly used to denote generators, transformers, or power supplies. It is universally recognized in engineering standards such as IEEE and IEC.

Used in educational materials, technical documentation, circuit simulation software, and engineering textbooks to denote AC power sources; matches user intent for learning circuit symbols or designing electrical systems.
