The difference in electric potential between two points, which is defined as the work needed per unit of charge to move a test charge between the two points. To calculate the power of any particular component in a circuit, multiply the voltage drop across it by the current running through it. The watt is the unit that desc ribes the rate at which energy is used by an electrical device. 116 0 obj<>stream
