      Energy - (E) joules (J), watt-hour (W·h), kilowatt-hour (kW·h) *Remember, whenever you are using joules, you need time to be in seconds. Whenever you are using watt-hours you need time to be in hours. Example #2. Calculate the power rating of an electric kettle if the heating element has a resistance of 9.5 Ω and the operating voltage is 120V.

      A kilowatt-hour is a unit of energy (NOT power) used by electric companies to calculate consumption as will be shown in the next example. Example 3: Assuming electrical energy costs $0.12 per kilowatt-hour, calculate the cost of operating an electric oven 4 hours a day for one year if the oven draws a current of 20.0 A at 120 V.
