Calculate or convert the electrical units of Voltage (volts), Current (Amps), Resistance (Ohms) or Power (Watts) in an easy use to use app.
Use the Ohms Law formula to quickly calculate your required Ohms Law parameters from ANY two values, enter any two values to calculate the remaining two.
Ohms Law Calculator Features
- Calculate Resistance (ohm's)
- Calculate Power (watts)
- Calculate Voltage (volts)
- Calculate Current (amps)
Ohms Law Formula
V / I * R (or P)
V = Voltage (Volts)
I = Current (Amps)
R = Resistance (Ohms)
P = Power (Watts)
How to use the Ohms Law calculator:
1) Enter any two values to calculate the other two.
2) Tap calculate.
Voltage Calculator Current Calculator Resistance Calculator & Power Calculator all in one app.
