## DC watts to volts calculation

So The voltage V in volts (V) is equal to the power  P in watts (W), divided by the current  I in amps (A).

V(V) = P(W) / I(A)

#### Example 1

What is the voltage in volts when the power consumption is 55 watts and the current flow is 3 amps?

V = 55W / 3A = 18.33V

#### Example 2

What is the voltage in volts when the power consumption is 75 watts and the current flow is 3 amps?

V = 75W / 3A = 25V

#### Example 3

What is the voltage in volts when the power consumption is 90 watts and the current flow is 3 amps?

V = 90W / 3A = 30V

## AC single phase watts to volts calculation

So The RMS voltage V in volts (V) is equal to the power  P in watts (W), divided by the power factor  PF times the phase current  I in amps (A).

V(V) = P(W) / (PF × I(A) )

#### Example 1

What is the RMS voltage in volts when the power consumption is 230 watts, the power factor is 0.8 and the phase current is 3.75 amps?

V = 230W / (0.8 × 3.75A) = 76V

#### Example 2

What is the RMS voltage in volts when the power consumption is 350 watts, the power factor is 0.8 and the phase current is 3.75 amps?

V = 350W / (0.8 × 3.75A) = 116V

#### Example 3

What is the RMS voltage in volts when the power consumption is 330 watts, the power factor is 0.8 and the phase current is 4 amps?

V = 330W / (0.8 × 4A) = 103V

## AC three phase watts to volts calculation

#### Calculation with line to line voltage

So The line to line RMS voltage VL-L in volts (V) is equal to the power  P in watts (W), divided by square root of 3 times the power factor  PF times the phase current  I in amps (A).

VL-L(V) = P(W) / (3 × PF × I(A) ) ≈ P(W) / (1.732 × PF × I(A) )

#### Example 1

What is the RMS voltage in volts when the power consumption is 230 watts, the power factor is 0.8 and the phase current flow is 2.165 amps?

V = 230W / (3 × 0.8 × 2.165A) = 76V

#### Example 2

What is the RMS voltage in volts when the power consumption is 350 watts, the power factor is 0.8 and the phase current flow is 2.165 amps?

V = 350W / (3 × 0.8 × 2.165A) = 116V

#### Example 3

What is the RMS voltage in volts when the power consumption is 330 watts, the power factor is 0.8 and the phase current flow is 3.165 amps?

V = 330W / (3 × 0.8 × 3.165A) = 75V

#### Calculation with line to neutral voltage

So The line to neutral RMS voltage VL-N in volts (V) is equal to the power  P in watts (W), divided by 3 times the power factor  PF times the phase current  I in amps (A).

VL-N(V) = P(W) / (3 × PF × I(A) )
