VA to voltage calculator
Easily convert apparent power (VA) to voltage using current (A) or load resistance. Perfect for electrical design, testing, and equipment rating checks.
apparent power to voltage
To calculate the voltage we use the apparent power divided by the current or square root the power multiplied by resistance in order to get the voltage in VA. This calculator makes calculations in real time.
Formula & Table Summary:
Known current: \( V = \frac{S}{I} \)
Known resistance: \( V = \sqrt{S \times R} \)
watts to volts tool
The VA to Voltage Calculator is a fast converter of apparent power- volt-amps (VA)- to voltage ( V ) when either current or load resistance is known. Apparent power combines both real power (watts) and reactive power (VAR) and it is essential in the AC systems. This calculator employs the simple electrical relations to calculate voltage based on VA. In the resistive loads, power, voltage and current are related bearing in mind the expression of Ohm. It can be used to vet electrical ratings, size transformers, or test the outputs of power supplies by engineers, electricians and students. Input the VA value and either current (A) or resistance ( ) and you can obtain correct voltage instantly.
