Current and resistance equation
WebEquation 2 relates the rate at which an electrical device consumes energy to the current at the device and the resistance of the device. Note the double importance of the current in the equation as denoted by the square of current. Equation 2 can be used to calculate the power provided that the resistance and the current are known. WebApr 7, 2024 · Rearrange V = IR to solve for resistance: R = V / I (resistance = voltage / current). Plug the values you found into this formula to solve for total resistance. For example, a series circuit is powered by a 12 volt battery, and the current is measured at 8 amps. The total resistance across the circuit must be R T = 12 volts / 8 amps = 1.5 ohms.
