How to convert Amps to Ohms

Amps to ohms calculation formula with volts

R_(Ω) = V_(V) / I_(A)

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

So,

Ω = V / A
ohms = volts / amps

For example:

Voltage (V) = 110V
Phase current (I) = 2,5A

Resistance (R) = 110V / 2,5A = 44Ω

Amps to ohms calculation formula with watts

R_(Ω) = P_(W) / I_(A)²

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

So,

Ω = W / A²
ohms = volts / amps²

For example:

Power (W) = 300W
Phase current (I) = 2,5A

Resistance (R) = 3000W / 2,5A² = 48Ω
