| alternating current |
A type of electrical current in which the direction of the flow of electrons switches back and forth. In the US, the current that comes from a wall outlet is alternating; it cycles back and forth sixty times each second. The current that flows in a flashlight, on the other hand, is direct current (DC), which does not alternate.

| alternating current |
Either voltage or current that varies smoothly from zero to a maximum value in one direction, or polarity, and returns to zero. It then reverses its direction (polarity) and rises to a maximum value in the opposite direction, and then returns to zero to complete the cycle. This cycle is repeated continuously. The number of cycles per second is its frequency, measured in hertz (Hz). See SINE WAVE.
