Explanation / Answer

Solution:

As we know;

The ratio of a transformer's output voltage (secondary voltage) to its input voltage(primary voltage) is equal to the

ratio of the transformer's output (secondary) turns to its input (primary) turns.

i.e,

Vs / Vp = Ns / Np

=> Vs = (900/400)*50

=> Vs = 112.5 Volts
