Alternating Current and Voltage - Engineering

Q1:

The average value of a 12 V peak sine wave over one complete cycle is

A 0 V

B 1.27 V

C 7.64 V

D 6.37 V

ANS:A - 0 V

It's so simple. As it's told here that peak value is 12 V over the entire sine wave and there are two halves of sine wave. One is positive half and another is negative half. So, the peak value of positive half would be 12 V and the peak value of negative half would be -12 V. Now if we go for evaluating the average value then we have to calculate in the following way: 12 + (-12)/2 i.e; equal to 0 (zero).
