Calculation Formula

Voltage (V) = Power (W) / Current (A)

Where:
V = Voltage in Volts
W = Power in Watts
A = Current in Amps

Result

Voltage: 0.00 Volts

Watts to Voltage Converter Calculator Usage Guide

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

How to Use the Calculator

  1. Enter the power consumption of your device in watts (W) in the "Power (Watts)" field.
  2. Enter the current draw of your device in amps (A) in the "Current (Amps)" field.
  3. Click the "Calculate" button to compute the voltage.
  4. The result will be displayed in volts (V).

Working Principle

This calculator uses the basic electrical formula:

Voltage (V) = Power (W) / Current (A)

This formula is derived from Ohm's Law and is valid for direct current (DC) circuits. For alternating current (AC) circuits, additional factors such as power factor would need to be considered.

When to Use This Calculator

  • When selecting a power supply for an electronic device.
  • When determining if an existing power supply can power a new device.
  • When calculating the voltage requirements for a circuit with known power and current.
  • When designing electrical systems where voltage needs to be calculated from power and current.

Example

If you have a device that consumes 50 watts (W) and draws 0.5 amps (A), the voltage can be calculated as:

Voltage = 50 W / 0.5 A = 100 V
