DC Power Calculator
Enter 2 values to get the other values and press the DC Power Calculator button:
Voltage (V) calculation from current (I) and resistance (R):
V(V) = I(A) × R(Ω)
Complex power (S) calculation from voltage (V) and current (I):
P(W) = V(V) × I(A) = V 2(V) / R(Ω) = I 2(A) × R(Ω)
Electric power is defined as the rate, per unit time, at which an electric circuit transfers its electrical energy. The SI unit of power is watt, one joule per second. A simple online power calculator to find out the power from the given values of voltage and current. Use this online DC Current Calculator to know the power output of your circuit for free. Enter the values for voltage in volts, current in amps in this DC voltage calculator and submit to know the power in watts.
