Electric Power Using Resistance and Voltage

Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit.

The power equals the voltage squared divided by the resistance.

Formula

QuantityVariable["P", "Power"] == QuantityVariable["V", "ElectricPotential"]^2/QuantityVariable["R", "ElectricResistance"]

symbol description physical quantity
P power "Power"
R electric resistance "ElectricResistance"
V voltage "ElectricPotential"
