The best free DC Power Calculator (2023)
The best free DC Power Calculator DC power calculation Voltage (V) calculation from current (I) and resistance (R): V(V) = I(A) × R(Ω) power calculation from voltage (V) and current (I): P(W) = V(V) × I(A) P(W) = V 2(V) / R(Ω) P(W) =I 2(A) × R(Ω) Where : I = current R = Resistor Ω V = volt V P = power W
