Sin wave have both positive and nagetive peaks. So the average value is 0.

Rishabh modi said: 10 years ago

For 1 complete cycle of average voltage v = 2*v(peak value)/3.16.

Santhi said: 1 decade ago

Avg value = 0.637 * peak
= 0.637 * 12
=7.64v

But why we didn't used the "avg value = 0. 637 * peak" ?

Sunil Malappuram said: 9 years ago

Average value over complete sine cycle is always zero.
