#### Calculating the DC watts to volts

V (V) = P (W) / I (A), where the voltage in volts is calculated by dividing the power in watts by the current in amps.

##### For example;
If the power consumption is 54 watts with a current flow of 8 Amps, what is the voltage in volts?

##### Solution
V (V) = P (W) / I (A)

= 54 W / 8A = 6.75 volts (V)

#### Calculating the AC single phase watts to volts

V (V) = P (W) / (PF x I (A)), which means that the voltage RMS in volts is computed by dividing the power in watts by the power factor multiplied by the phase current in amps.

##### For example;
The power consumption is 413 watts with a power factor of 0.6. What is the RMS voltage when the phase current is 4.89 amps?

##### Solution
V (V) = P (W) / (PF x I (A))

= 413 W / (0.6 x 4.89 A) = 140.76 volts (V)

#### Calculating the AC three phase watts to volts

##### Line to line voltage
V L-L (V) = P (W) / (√3 x PF x I (A)), which means that the line to line voltage RMS in volts is computed by dividing the power in watts by the multiplication of square root of three by the power factor times the phase current in amps.

##### Line to Neutral voltage
V L-N (V) = P (W) / (3 x PF x I (A)), where the line to neutral voltage RMS in volts is calculated by dividing the power in watts by three multiplied by the power factor times the phase current in amps.
