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 solenoid is connected to a battery so that a steady current flows through it. If an iron core is inserted into the solenoid, then

Assertion (A) : A lamp is connected in series with a capacitor and ac source connected across their terminal consequently current flow in the circuit and the lamp will shine. Reason (R ) : Capacitor block dc current and allow ac current

A constant current I is maintained in a solenoid. Which of lthe following quantities will increase if an iron rod is inserted in the solenoid along its asix?

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

A solenoid is connedted to a source of constant EMF for a long time. A sof iron piece is inserted into it. Then :
