Why using this formula?

Kva in primary = kva in secondary.
Maximum load = 8A = secondary current.
Secondary voltage = 2KV.
.'.KVA = Secondary current * Secondary voltage.
= 8*2*1000.
= 16Kva.
Maximum load = 8A = secondary current.
Secondary voltage = 2KV.
.'.KVA = Secondary current * Secondary voltage.
= 8*2*1000.
= 16Kva.

In transformer copper loss is depends on current ( I^2 R ) and core loss is depends on voltage, so only the rating of transformer is expressed in KVA.
So KVA = secondary current x secondary voltage.
KVA = 8 x 2.
KVA = 16 KVA.
So KVA = secondary current x secondary voltage.
KVA = 8 x 2.
KVA = 16 KVA.

The given power is reactive power so how can we say it is a load,
Because reactive power did not require for a load but it work only with inductor and capacitor.

When transformer output rating in MVA then how can get the answers?

WE KNOW THAT,
POWER ON LOAD SIDE,
SO,
P = V2*I2.
P = 8A*2KV = 16 KVA.
POWER ON LOAD SIDE,
SO,
P = V2*I2.
P = 8A*2KV = 16 KVA.

Transformer rating is in KVA(Apparent Power).
Apparent power = V*I = 2KV*8A = 16 KVA.
Apparent power = V*I = 2KV*8A = 16 KVA.

Transformer output power rating in KVA.
KVA = V X I = 2X8 = 16.
KVA = V X I = 2X8 = 16.

Power = Voltage*Current.
Power on load side = V2*I2.
Here P = 2kv*8A.
=16kvA.
Power on load side = V2*I2.
Here P = 2kv*8A.
=16kvA.

What will happen if t/f is made from magnet in place of iron?
