Assertion (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.
Reason (R ) : If iron rod is inserted in solenoid, the induction of solenoid increases.

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.

Assertion: A bulb connected in series with a solenoid is connected to AC source. If a soft iron core is introduced in the solenoid, the bulb will glow brighter. Reason: On introducing soft iron core in the solenoid, the inductance increases.

A bulb connected in series with an air-cored solenoid is lit by an a.c. source. If a soft iron core is introduced in the solenoid.

A bulb connected in series with a solenoid is lit by a.c. source. If a soft iron core is introduced in the solenoid, will bulb glow brighter ?
