A step-up transformer is operated on a 2.5 kV line

A step-up transformer is operated on a 2.5 kV line. It supplies a load with 20 A. The ratio of the primary winding to the secondary is 10 : 1. If the transformer is 90% efficient, calculate
(i) the power output
(ii) the voltage and
(iii) the current in the secondary

Given,input voltage, { V }_{ P } = 2.5 x {{10}^{3}} V
Input current { I }_{ P } = 20A
