Ohm Law Calculator

Ohm's Law calculators are available for calculating current, voltage, resistance, and power. You can input two of the four factors in Ohm's Law, which are Power (P) or (W), measured in Watts, Voltage (V) or (E), measured in Volts, Current or Amperage (I), measured in Amps (Amperes), and Resistance (R), measured in Ohms.

The required factor will be calculated automatically when you enter the necessary value.

The various formulas for Ohm's law are as follows:

P = power in watts
E = voltage in volts
I = current in amps
R = resistance in ohms

P = E2 / R
P = I2 * R
P = E * I

E = sqrt(P * R)
E = P / I
E = I * R

I = E / R
I = P / E
I = sqrt(P / R)

R = E / I
R = E2 / P
R = P / I2
