For a transformer power is always constant.

Its so simple an ideal transformer is free from losses so whatever the power is supplied to the primary winding the same power is delivered at output. So its obviously 25w.

@Srinivas.
Transformer is a constant flux power and frequency but for practical transformer we have to calculate core losses and copper losses and output = input-total losses from this calculate efficiency = output/input.

V1I1 = V2I2 (for IDEAL transformer) means power constant.

In a ideal TXR does not any type loss so that i/p power = o/p power.

For ideal T/F, efficiency 100%.
Hence o/p = i/p.
i.e, 25.
Hence o/p = i/p.
i.e, 25.

First of all power factor is not given which is different for input side and output side. So active power can never be equal apparent power can only be equal KVA should be equal on both sides not KW. Whether it is ideal or practical we can't say active power is equal or not.

For an ideal transformer the input is equal to the output.

Is there any difference between power and rating of transformer?
Because in above problem they have given power in W, where as rating is given in KVA.

If the transformer is ideal then,
Input power = Output power.
Answer is 25W.
Input power = Output power.
Answer is 25W.
