Show graphically that the average of sinusoidally varying current in half cycle may of may not be zero.

Text Solution

Verified by Experts

Figure show two parts A and B, each half cycle. In part A we can see that net area is zero.
`therfore lt I gt` in part A is zero.
In part B area is positive hence in this part `lt I gt ne=0`

These question consists of two statements each linked as Assertion and Reason. While answering these question you are required to choose any one of the following five responses. Assertion: Average value of current in half the cycle an AC circuit can't be zero. Reason: For positive half cycle average value of current is 2/pi i_(0) , where i_(0) is the peak value current. In time interval from t_(1) to t_(2) average value of current will be zero.
