KVA = ( VOLTS * AMP )/1000 = ( 2000 * 8 ) /1000 = 16

Suppose 2kv is given as 2v then what is the answer.

In short circuit test iron loss is negligible why?

kva rating = v × i = 2000 × 8 = 16000.

Why transformer's rating is in Kva and not in Kw?

Thank you for all the solution and explanation.

It's simple v2*i2=2kv*8
=16kv

Put the formula and get the answer KVA = VI.

V2*i2 = kVa.
So,
2* 8= 16 kVa.
Ans:- 16 kVa.

Here how we can assume power-factor values?
