AC power from an outlet can be described as .
A) An adaptive current

C) A sine wave
D) A square wave

Question

Quizplus · Accepted Answer

AC power from an outlet is a sine wave, which oscillates back and forth in a repeating pattern. This is represented by a waveform that shows the amplitude (voltage) of the current over time. A square wave would be a constant on/off pattern and a continuous direct supply of current refers to DC power not AC. An adaptive current is not a common term used to describe AC power.
