Solution

The correct option is D

60Hz


  1. Transformer is a device used to increase or decrease the voltage or current.
  2. There are two types of the transformer - step up and step down.
  3. Transformer changes the voltage or current level without modifying the frequency of the signal.
  4. Therefore, whatever the turn ratio is, the output frequency will be equal to the input frequency.
  5. Therefore, the frequency of the output is 60Hz.

Hence, option (d) is correct.
