When we study mutual induction between two coils,the secondary coil circuit consists of:
Correct answer: C. A galvanometer only
- A. A rheostat and battery
- B. A battery only
- C. A galvanometer only
- D. A rheostat only
Explanation
In a typical setup studying mutual induction between two coils, the secondary coil circuit usually consists of: A galvanometer only. The purpose of the galvanometer is to detect the presence and direction of current induced in the secondary coil by changes in magnetic flux from the primary coil. It's used to observe the effects of mutual induction.

About Electromagnetic Induction
Changing magnetic flux induces an emf according to Faraday's law, while Lenz's law gives the direction that opposes the change producing it. Transformers apply induction between coils to step alternating voltage up or down, with turns ratio, current transformation and energy losses determining practical operation.
