Ohms to Amps calculator

Ohms to Amps calculation with volts

Enter the voltage in volts (V), resistance in ohms (Ω), then press the Calculate button to get the result in amps (A).

Voltage in volts (V)
Resistance in ohms (Ω)

I(A) = V(V) / R(Ω)

The current I in amps (A) is equal to the voltage V in volts (V), divided by the resistance R in ohms (Ω).

Ohms to Amps calculation with watts

Enter the power in watts (W), resistance in ohms (Ω), then press the Calculate button to get the result in amps (A).

Power in watts (W)
Resistance in ohms (Ω)

I(A) = √ (P(W) / R(Ω))

The current I in amps (A) is equal to the square root of the power P in watts (W), divided by the resistance R in ohms (Ω).
