Question

For a step up transformer, number of turns in the primary windings is the number of turns in the secondary windings.

• A. greater than
• B. lesser than
• C. same as

Answer 1

The correct option is B lesser than

For a solenoid, induced emf depends on the number of turns in the solenoid. Therefore, in a step up transformer, to increase the voltage, number of turns in the secondary windings has to be greater than the number of turns in the primary windings.
