How many kilowatts is a kilovolt ampere

The difference between kilovolt ampere of alternating current and kilowatt is that kilowatt refers to active power, and kilovolt ampere includes active power and reactive power, which is involved in the study of alternating current or electrical power supply;
Usually, in the pure resistive load circuit, because the reactive power is 0, 1 KVA on the circuit can be equal to 1 kW, but in the non pure resistive load circuit, the product of voltage and current does not work completely, so the number of KVA on the circuit = kW / the power factor of the circuit;
Generally, when the power factor is 0.9, the capacity of 1 KVA can only output 0.9 kW

How much W is 1000mA 12V equal to 4.5va, and how much W is 220V equal to

1000mA 12V
I estimate that it's lower case Ma, 1000 Ma is 1a, power is 1A times 12V, equal to 12 watts. Generally, there is no big Ma, if it's big Ma, it's 12 MW
4.5VA 220V
VA is volt ampere, another expression of Watt, so the power is 4.5 watt

Is 1A current equal to 0.8kw
In other words: how much load does 10A meter bear?

Current multiplied by voltage equals power
1A*220V=220W
10A*220V=2.2KW

What is the current 1A equal to?

1A=1000mA
