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.
