What is meant by Sinusoidal alternating voltage ?

Explanation

If the waveform of alternating voltage is a sine wave, then it is known as sinusoidal alternating voltage which is give by the realtion.
`v=V_(m)sinomega`
where `I_(m)` is the maximumj value (amplitude) of the alternating current. The direction of sinusoidal voltage or current is reversed after every half-cycle and its magnitude is also changing continuously.
