Guys, some come across true power and apparent power and some tell us about copper lose and core loss but I am convinced with @Santosh answer after that @Sudipt told there will be no pf then its tricky again want to know pf should be considered or not in calculation.

How we can calculate if kva is given and we have to find out maximum current rating 2kva transformer find max current rating?

V*A = 8*2 = 16 kva.

Kva = V *I = 2KV* 8A = 16 KVA.

There are lot of factors to find a transformer single or three phase,
1. Ratings.
2. No of windings.
3. Size (may be).
1. Ratings.
2. No of windings.
3. Size (may be).

How to we know the transformer is single phase or three phase?

Because of two type losses in transformer (Core losses and iron losses. Core losses occur from voltage and iron losses occurred from currant) is T/F rating in KVA.

But friend transformer reading in kva.
That means p = vi cos phi power factor.
That means p = vi cos phi power factor.

Transformer always rating in KVA that means voltage *current.
So 8*2 = 16 KVA.
So 8*2 = 16 KVA.

Simple KVA = voltage*current.
So as per the question we know voltage = 2kva and current = 8A.
So 2*8 = 16kva.
So as per the question we know voltage = 2kva and current = 8A.
So 2*8 = 16kva.
