If power is 100 W and voltage is 50 V, what is the current?

Power relates to voltage and current through P = V × I. With a power of 100 W and a voltage of 50 V, the current is I = P / V = 100 W ÷ 50 V = 2 A. So at 50 volts, carrying 2 amperes delivers 100 watts. If the current were 1 A, the power would be 50 W; at 3 A, it would be 150 W, and at 4 A, 200 W, which helps confirm why 2 A is the correct value.
