Electric Power Using Resistance and Current

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

The power equals the current squared times the resistance.

Formula

QuantityVariable["P", "Power"] == QuantityVariable["I", "ElectricCurrent"]^2*QuantityVariable["R", "ElectricResistance"]

symbol description physical quantity
P power "Power"
I electric current "ElectricCurrent"
R electric resistance "ElectricResistance"
