Ohm's Law Calculator

Enter any two known values and press "Calculate" to solve for the others.

Voltage (E) = Current (I) * Resistance (R)
Power (watts) = Voltage (E) * Current (I)

Voltage (E):		Volts (V)
Current (I):		amps (A) milliamps (mA)
Resistance (R):		ohms (Ω) kilohms (kΩ) megaohms (mΩ)
Power (P):		Watts (W)
