When an electric heating element is connected to a 110 V circuit and a current of 3.2 A is flowing through the element. how much energy is used up during a period of 5 hours by the element

A. With a speed of 300,000,000 m/s
B. Through a relatively short distance .
C. Back and forth between the ends of the conductor
D. From one end of the conductor to the other end

D) From one of the conductor to the other end

The power being used momentarily is 110V x 3.2A = 352W

During a period of 5 hours:  352W * 5h = 1760 Wh = 6336kJ
