Ohms Law Calculator

The Ohms Law Calculator or Ohms Calculator will estimate the value of voltage, current, resistance, and power based on the Ohms Law. Input any two variables in the calculator to find the remaining two variables.

Ohm’s Law Equations

Ohm’s Law Calculator works on the basis of Ohm’s Law equations.
The Ohm’s Law equations are:
V = (I x R)
R = (V / I)
I = (V / R)
P = (V x I)
P = (V2 / R)
P = (I2 x R)
where: V: Voltage
R: Resistance
I: Current
P: Power
