Electrical energy EE is supplied at a constant power PP (expressed in kilowatt) for a time tt (expressed in hour). Which of the following expressions gives EE in joule? a) E=1000 P t×360E = 1000\,P\,t\times360 b) E=1000 P t×3600E = 1000\,P\,t\times3600 c) E=P t×3600E = P\,t\times3600 d) E=1000 P t×60E = 1000\,P\,t\times60
