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.

100 watt is equal to how many va?
100VA
Does the primary winding VA equal the secondary winding VA when a transformer is loaded?
no becouse transformer function depends on no of coil in primary and secondry coil
What does 24vac 4.8va equal in amps?

How many acres in Fauquier County VA?
Fauquier County, VA covers 416,640 acres.
How many decibel is equal to one Hz?
Impossible question, like asking "One Apple is equal to how many oranges" Simply set : Decibels it the unit of volume, how loud things go hertz is how fast things change, the frequency (number of changes per second). When you talk about music, different frequencies can have a different volume. You can even measure the volume in frequency ranges - look up : paragraphic equalizer for the principle. Geert Fieuw Beyond The Labyrinth ----------------------------------------------------------------------- +db= 10*log(p2/p1) +db= 10*log(2watts/1watt) +db= 10*log(2) +db= 10*.30103 +3.0103= 10*log(2watts/1watt) so double the power you gain 3db's so double the sound you gain 30dbs and p2 is 1000 times p1 +db= 10*log(p2/p1) +db= 10*log(1000watts/1watt) +db= 10*log(1000) +30= 10*3 test signal say 60 Hz

How many miles fro Richmond VA to Virginia Beach?
How many miles from Richmond VA is Virginia Beach, VA?
How many miles from Norfolk VA to Alexandria VA?
It is approximately 187 miles from Norfolk VA to Alexandria VA.
How many joules in 1watt?
You can't directly convert one to the other. A joule is a unit of energy, and a watt is a unit of power. 1 watt = 1 joule per second.
How many va equal to1kw?
There's no direct conversion, because it depends on the phase angle between the 'V' and the 'A' in each particular situation. The number of KW = 0.001 x (VA) x Power factor. On a DC line, the power factor is 1, so KW = KVA = VA/1,000
