Why I avg. (Current average) multiplied by Vavg (voltage average) and Time period does not give me heat loss in full cycle ? As I know I avg gives me dc component for ac ,I can take + I avg & -I avg for for +half cycle and -half cycle respectively,then net current will be zero in full cycle but both the current are responsible for heat production in ac so why can'take and do  I avg ×v avg×T= Heat produced in ac current . (I know that vrms ×Irms×T will give me heat loss ) But my quetion it is why it is wrong which I had first . thank you
