Formula

The formula to calculate Volts (V) from Power (W) and Current (A) is:

For DC:

\[ V (\text{V}) = \frac{P (\text{W})}{I (\text{A})} \]

For Single Phase AC:

\[ V (\text{V}) = \frac{P (\text{W})}{I (\text{A})} \]

For Three Phase AC:

\[ V (\text{V}) = \frac{P (\text{W})}{I (\text{A}) \times \sqrt{3}} \]

Where:

Watt to Volt Definition

Watt (W) is a unit of power, representing the rate of energy usage per time unit. Volt (V) is a unit of electric potential, representing the potential difference between two points. The conversion from watts to volts depends on the current and the phase of the circuit.

Example Calculation

Let's assume the following values:

Using the formula for Single Phase AC:

\[ V = \frac{1000}{5} \]

\[ V = 200 \text{ V} \]

The Voltage (V) is 200 V.
