## 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 / A ^{2}*

*ohms = volts / amps*

^{2}**For example:**

*Power (W) = 300W*

*Phase current (I) = 2,5A*

*Resistance (R) = 3000W / 2,5A ^{2} = 48Ω*
