In Ac Sine Wave?

The waveform of an alternating current power circuit is a sine wave. ... When a vector points upward along the y-axis, the voltage or current has reached its positive maximum value, and when it points downward along the same axis, the negative maximum has been reached. The horizontal x-axis indicates a value of zero.

Why AC is a sine wave?

But in basic circuit analysis and AC signal analysis, we tend to use sine waves because they are the easiest to generate (as compared to square/ramp signals) as well as the easiest to analyze mathematically (all our calculus tools work wonderfully for curves like the sine, but tend to be more inconvenient around things ...

Is AC a sinusoidal wave?

The term AC or to give it its full description of Alternating Current, generally refers to a time-varying waveform with the most common of all being called a Sinusoid better known as a Sinusoidal Waveform.
