A 20 kva 4400220 v transformer with an equivalent impedance

A 20 kVA, 4400/220 V transformer with an equivalent impedance of 0.01 Ω is to operate in parallel with a 15 kVA, 4400/220 V transformer with an equivalent impedance of 0.015 Ω. The two transformers are connected in parallel and made to carry a load of 25 kVA. Assume both the impedances to have the same angle.

(a) Find the individual load currents.

(b) What per cent of the rated capacity is used in each transformer?
