I need help on a science question: An electric fan uses 3,240,000 J when running 2.5 hours. If it is plugged into a standard 120 V wall outlet, how much current does it draw?


As we know that Current = charge/time in seconds, engery=0.5capacitancesquare of voltage from this find capacitance capacitance = (2energy)/square of voltage capacitance = (23240000)/square of(120) = 450 F and charge = capacitance * voltage = 450120 = 54000 C so current = 54000/(2.53600) = 6 Amperes. Hence answer for your question is 6 Amperes
