WebMay 23, 2011 · Voltage is a measure of how much a single electron's energy changes across the circuit. Current is how many electrons are flowing through a circuit. Multiply those two values to get the rate of energy transfer, or power. WebOne watt-hour is equal to 3600 Joules (3.6 kJ). Below is a quick conversion equation. W h = E 3600 W h = E 3600 Where: Wh = Energy consumed for a period of time in watt-hours E = Energy dissipated in a resistive element in joules Further Reading Textbook—Voltage and Current Textbook—DC Circuit Equations and Laws Worksheet—Energy, Work, and Power
