In a.c. circuits, the watt is used to measure the true power of a load, and is determined by multiplying the supply voltage by the load current by the power-factor of the load. The volt ampere is used to measure the apparent power of a load, and is determined by multiplying the supply voltage by the load current. So the relationship between the watt and the volt ampere depends on the power factor of the load. For example a 100 VA load with a power factor of 0.8 (leading or lagging) will have a true power of 80 W.
Its a bit of a trick question. 1 watt is one volt-amp except in situations where the power factor has increased or decreased that ratio. For instance with a power factor of .8 a volt-amp is equal to .8 watts. So with a perfect power factor 1 kva (kilo-volt-amp) is equal to 1 kilowatt. But if the power factor is something other then 1 you can find it by pf*w=va.
Watts (W) is calculated by multiplying Volts (V) times Amps (A), so 1W = 1VAAnswerIn a.c. circuits, the watt is used to measure the true power of a load, and is determined by multiplying the supply voltage by the load current by the power-factor of the load.

no becouse transformer function depends on no of coil in primary and secondry coil

1000 VA = 1 kva
1000 VA = 1 kva
Allie Watt died March 15, 1968, in Norfolk, VA, USA.
k is 1000 V is volts A is amps basic algebra kVA = (V * A)/1000 120 Volt with 20 Amp would be: (120 * 20)/1000 = 2.4 kVA
VA stands for Volt-ampere. 1 VA is equal to 1 Watt. So 600va is about 600 watts. This can be confusing because a power supply rated at 600va will not put out 600 watts due to reactance. The power supply contains an inductor or capacitor so the actual output will be around 1/2 to 2/3 of the VA.

Electricity has three terms. Active power - Watt. Apparent power VA, reactive power VAR. Watt is known as active output

You must get 100% (none of them wrong) and 80% (3 of them wrong) to still pass the VA permit test.
No difference in case of DC. In case of AC Watt refers to Power which includes the factor of power factor. VA does not include power factor.
kVA means thousands of VA. For DC, a VA (volt times ampere) is really a watt. For AC, it may be a watt, but it may also be a bit less, depending on the power factor. The power factor takes into account the fact that voltage and current may be slightly out of phase. However, for most practical applications the power factor is usually close to one.
