Convert Watts (W) to Volt-Amps (VA)
To convert Watts to VA,Please provide the values below:
To calculate watts to volt-amps, use the following formula:
The Real Power in Wattsis equal to the Apparent Power in Volt-amps multiplied by the Power factor (pf)
For example,
If an Induction motor takes 10000W active power at 0.95 (lag) power factor from the AC source. Calculate the VA rating of the motor.
Answer
Where,
Active power P = 10000W , Pf = 0.95
S (VA) = Pw ÷ Pf
S (VA) = 10000 ÷ 0.95
S (VA) = 10526.32
VA = 10526.32

Frequently Asked Questions:
What do you convert watts to volt-amps for ?
When you calculate equipment loads, fuses and wire sizes, you convert watts to VA and device capacity is written in VA, so watts are converted to VA.
What is DC Circuit 1 watts in volt-amps (VA) ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 01 watt is the equivalent of 1 VA.
What is AC Circuit 100 watts in volt-amps (VA) ?
A watt changes depending on whether the electrical circuit is AC or DC. In a DC circuit, 100 watts is the equivalent of 117.65 VA. This equivalence means that the power factor of that power supply is 0.85.
What is the formula for watts to volt-amps ?
Apparent Power(VA) = Real Power(Watts) / Power factor in PF.
