## Ohms to volts calculation formula with amps

V_{(V)} = I_{(A)} × R_{(Ω)}

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

So,

*V = A × Ω*

*volt = amp × ohm*

**For example:**

*Current (I) = 0,5A*

*Resistance (R) = 30Ω*

*Voltage (V) = 0,5A x 30Ω = 15V*

## Ohms to volts calculation formula with watts

V_{(V)} = √ (P_{(W)} × R_{(Ω)})

The voltage **V** in volts (V) is equal to the square root of the power **P** in watts (W), multiplied by the resistance **R** in ohms (Ω).

So,

*V = √ (W × Ω)*

*volt = √ (watt × ohm)*

**For example:**

*Power (P) = 10W*

*Resistance (R) = 6Ω*

*Voltage (V) = √ (10W x 6Ω) = 7,746V*
