When current flowing in an inductive circuit is switched off, the induced current will be

A in the opposite direction as the main current
B equal to the main current
C in the same direction as the main current
D zero

Verified Solution

Answer & Solution

Correct Answer

(C) in the same direction as the main current

Step-by-step Solution

Detailed explanation

The induced current will be in the same direction as the main current. When the current flowing in an inductive circuit is switched off, the magnetic flux associated with the coil decreases. According to Lenz's law, the induced current flows in the same direction as the main…

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
