Statement (A): An electric lamp is connected in series with a long solenoid of copper with air core and then connected to AC source. If an iron rod is inserted in solenoid the lamp will become dim.
Statement (B): If iron rod is inserted in solenoid, the induction of solenoid increases.
Statement (B): If iron rod is inserted in solenoid, the induction of solenoid increases.
View answer and explanation
Correct option: A
Both (A) and (B) are true
Option A (Both (A) and (B) are true) is correct because inserting an iron rod increases the solenoid's inductance, which increases impedance and dims the lamp.
