Figure below shows a bulb connected in an electrical circuit.
1. When the key is switched ON the bulb obtains maximum glow only after a shorter interval of time which property of the solenoid is responsible for the delay?
- Self-induction
- Mutual Induction
- Inductive reactance
- None of the above
2. If the flux linked with the solenoid changes from 0 to 1 weber in 2 sec. Find the induced emf in the solenoid.
3. If the 3v battery is replaced by an AC source with the key closed, what will be observation? Justify your answer.
