Generally we know that ratings of transformer is denoted as kVA then from the given:
KV = 2.
Amps (A) = 8.
Then, (kVA) = 2*8 = 16 kVA.
KV = 2.
Amps (A) = 8.
Then, (kVA) = 2*8 = 16 kVA.

Load current means secondary current, already we know secondary voltage.
So output load is i*v=kva
i=8A and v=2KVA
So i*v=16kva.
So output load is i*v=kva
i=8A and v=2KVA
So i*v=16kva.

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

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).

Because all losses ( core losses and copper losses ) are calculated in kva. That is why transformer is rated in kva.

The rating of transformer is given in KVA because the what type of load will connect with the x"mer is not defined.

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.

The rating of transformer is represented in kilo volt so that it is divided by 1000, one kilo means 1000.

Because of we find kva that means we have to multiply with current so that.
Ans= 2kv*8 (given) =16kva.
Ans= 2kv*8 (given) =16kva.

KVA=V1*I1=V2*I2
KVA=(2000*8)/1000
it is divided by 1000 because it is representing in kva
KVA=16KVA
KVA=(2000*8)/1000
it is divided by 1000 because it is representing in kva
KVA=16KVA
