let me answer you in layman terms. you can say 1000VA means 1000watt (like in DC circuit).

All electrical devices are made of various components. Two very important components which you would find in almost all the electrical devices are capacitor and inductor.

Now due to these components you will not receive all the power i.e.1000watt.

It might be 980watt. Now the actually power was 1000, which is called apparent power,

but power transmitted was 980, which is called, real power because that is what reached at the end terminal.

But in real terms volt-ampere or VA is unit of apparent power in an AC circuit containing capacitive or inductive reactance(reactance is opposition caused by electronic components to ac current due to capacitance or inductance). Apparent power is the product of source voltage and current i.e. 1VA is the power dessipated when one volt produce one ampere current.

The term VA (Volt Amps) is used when specifying the output capacity of a generator, rather than using Watts (Or Kilowatts). The reason for this is that the designer of the generator has no idea what sort of load will be applied.

The problem is that many types of load have a power factor (PF) of less than 1. Loads that are reactive will cause the current to be out of phase with the voltage, and thus present lower power factors. So a generator that is delivering 120 volts at a current of 8.33 amps is said to be outputting 1000VA. If the load is purely resistive (Lamp bulbs, but not CFL's) It will also be outputting 1000W.

1mva equal to how many kw?

Basically VA is the same as watt. Kilo means thousand, Mega (abbreviatted M) means a million.AnswerThe watt and the volt ampere are used to measure two different quantities and, so, cannot be directly converted one to the other. The watt is used to measure 'true power', while the volt ampere is used to measure 'apparent power'.There is, though, a relationship between the two, as the true power of a load is equal to its apparent power multiplied by the power factor of that load. So, if you know the power factor (which can vary from 0 to 1), then you can determine the true power of a load, if you are given its apparent power.Incidentally, SI doesn't recognise either the volt ampere (apparent power) or reactive volt ampere (reactive power); all forms of 'power' are measured in watts in SI. The volt ampere and the reactive volt ampere are best described as 'traditional' units.


How source of 6 volt gives 1 ampere current and source of 18 volt gives 0.5 ampere at same resistance is it violation of ohms law?

yes


One volt is equal to?

One volt is the electric potential required to generate one ampere through one ohm. One volt is the electric potential involved when one ampere generates one watt of power. One volt is one joule per coulomb.

What is a volt-ampere the product of?

A volt - ampere is the unit for the product of voltage and current. This is power. Power = voltage x current. The unit of power is more usually called the watt. Volts x amps = watts.

How calculate kilovolt-ampere?

25kv=?kwAnswerA volt ampere (V.A) is the unit of apparent power, and applies to AC circuits that contain resistance and reactance. Apparent power is the vector sum of true power and reactive power. A kilovolt ampere is 1000 V.A. The volt ampere is the product of supply voltage and load current.
