Watts to Voltage Calculator Calculator Usage Guide

Learn how to use the Watts to Voltage Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the power (in watts) of the electrical device in the "Power (Watts)" field.
  2. Enter the current (in amperes) of the electrical device in the "Current (Amperes)" field.
  3. Click the "Calculate" button to calculate the voltage.
  4. The calculated voltage (in volts) will be displayed in the "Voltage (Volts)" field.

Working Principle

The Watts to Voltage Calculator uses the formula V = P / I, where V is the voltage, P is the power, and I is the current. This formula is derived from Ohm's Law and is used to calculate the voltage when the power and current are known.

Example

If an electrical device has a power of 100 watts and a current of 5 amperes, the voltage can be calculated as follows:

V = 100 W / 5 A = 20 V

Therefore, the voltage across the device is 20 volts.
