Ohm’s Law Calculator
Provide any 2 values and click “Calculate” to solve for the other electrical parameters.
Enter exactly two values below to calculate the remaining two values using Ohm’s Law and Power formulas.
Voltage (V)
V = I × R
Current (I)
I = V / R
Resistance (R)
R = V / I
Power (P)
P = V × I
