Solve for the change in energy using the power equation, and don’t forget to convert the given time of 5min into seconds (5min = 300s). P = ΔE/t, 1600W = ΔE / 300s, solving for ΔE = (1600J/s)*(300s) = 480,000J. 3. The utility charges you for energy in kilowatt-hours. If you simplify kilowatt-hours you will get just units of joules which is ...
How to Calculate Electric Power and Energy
Electrical power equation: Power = Volts x Amps. Energy from power: Energy = Power x Time. Light source A – 300W lamp. Light source B – 150W lamp. Light source C – halogen lamp.
