Transformers

Q1:

How many primary volts must be applied to a transformer with a turns ratio of 0.1 to obtain a secondary voltage of 9 V?

A 9 V

B 90 V

C 900 V

D 0.9 V

ANS:B - 90 V

We know that, V2/V1 = N2/N1.

Given V2 = 9v, N2/N1 = 0.1

Therefore, 9v/V1 = 0.1

V1 = 9v/0.1 = 90v. For more detail: Step Down Transformer - Circuit with Simulation.
