Transformers

Q1: What kVA rating is required for a transformer that must handle a maximum load current of 8 A with a secondary voltage of 2 kV?

A 4 kVA

B 0.25 kVA

C 16 kVA

D 8 kVA

ANS:C - 16 kVA

In the question, it is said that the load current is 8A and the secondary voltage is 2KV.

We know that the kva rating of a transformer remains constant be it in primary side or secondary side.
so,

V1*I1= V2*I2.
V2 = 2KV,
I2 = 8A.
