is the cost of the electricity bill for that quarter? Answers 1) The following quantities are measured in the following units; - Electric Current is measured in Ampere‚ A. - Inductance is measured in Henry‚ H. - Frequency is measured in Hertz‚ Hz. - Power is measured in Watts‚ W. - Energy (work) is measured in Joules‚ J. 2) AC 3) Power = Energy / Time‚ therefore Energy = Power x Time. i) 10 bulbs x 60 Watts = 600 Watts‚ 600 Watts x 6 Hours = 3600 Wh = 3.6 kWh per day.
