WebThe easiest way to calculate power in watts (W) dissipated by a resistor in a DC circuit is to use Joule’s law, P = I V P = I V, where P P is electric power. In this case, each resistor has the same full current flowing through it. By substituting Ohm’s law V = I R V = I R into Joule’s law, we get the power dissipated by the first resistor as WebThe formula for the power dissipated in a resistor is P = V 2 R The formula for the power dissipated in a resistor is P = I 2 R Check your Understanding 18.
