Statement I: An eletric lamp is connected in series with a long solenoid of copper with air core and then connected to an ac source. If an iron rod is inserted in the solenoid, the lamp will become dim.
Satement II: If an iron rod is inserted in the solenoid, the inductance of the solenoid increases.

A

Statement I is True, Statement II is True, Statement II is the correct explanation for Statement I.

B

Statement I is True, Statement II is True, Statement II is NOT the correct explanation for Statement I.

C

Statement I is True, Statement II is False.

D

Statement I is False, Statement II is True.

Text Solution

Verified by Experts

The correct Answer is:
A
If inductance of solenoid ioncreases, reactange of circuit also increases, then obsiously current will decreases and lamp becomes dim.
