Energy is transferred when an electrical circuit is complete. A simple circuit may consist of a battery, lamp and wires. Internal energy stored in the battery is transferred to moving charged…
Electrical energy calculations. The amount of electrical energy transferred to an appliance depends on its power and the length of time it is switched on. The amount of mains electrical energy transferred is measured in kilowatt-hours, kWh. One unit is 1 kWh. Electric Energy Formula. E = P × t. E is the energy transferred in kilowatt-hours, kWh, Energy transferred from electricity is worked out by: Energy = power × time E = P × t. Energy, E is measured in: joules (J) when the power is in watts and the time, t, is in seconds. kilowatt hours (kWh) when the power is in kilowatts and the time, t, is in hours. Example: A 800 W toaster is switched on for one minute. The energy used is: E = 800 W × 60 s
