Ohm's Law Calculator

V = IR
I = V/R
R = V/I
is the magic triangle of Ohm's Law !

The Ohm's law describes the relationship between the following electrical entities:

Voltage (Volts/V)
Current (Amps/A, I)
Resistance (Ohms/Ω, R)
Power (Watts/W)

Set any two values and the app will calculate the others for you!
