What is a Volts to Watts Calculator?

A Volts to Watts Calculator is a tool that converts voltage and current to power in watts. It helps in understanding the relationship between these electrical measurements in circuits and devices.

The Formula

The formula for converting volts to watts is:

\[P = V \times I\]

Where:

  • P is power in watts (W)
  • V is voltage in volts (V)
  • I is current in amperes (A)

Power Triangle

While not directly applicable to the volts to watts conversion, the power triangle is useful for understanding the relationship between different types of power in AC circuits:

Real Power (W) Apparent Power (VA) Reactive Power (VAR) θ

In this triangle:

  • The horizontal side represents real power (W)
  • The vertical side represents reactive power (VAR)
  • The hypotenuse represents apparent power (VA)
  • The angle θ is the phase angle between voltage and current
  • The cosine of θ is the power factor

Note that for DC circuits or AC circuits with purely resistive loads, real power (W) is equal to apparent power (VA), and there is no reactive power.
