Assertion: The possibility of an electric bulb fusing is higher at the time of switching ON and OFF.
Reason: Inductive effects produce a surge at the time of switch ON and OFF.

Assertion: The probability of an electric bulb fusing is higher at the time of switching ON and OFF . Reason: Inductive effects produce a surge at the time of switch OFF and switch ON .

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : The possibility of an electri bulb fusing is high at the time of switching ON and OFF. Reason : Inductive effects produce a surge at the time of switch -OFF and switch -OFF and ON.

(A): The possibility of an electric bulb fusing is higher al the time of switching on and off. (R): Inductive effects produce a surge at the time of switch-off and switch-on

Assertion : The electric bulbs glows immediately when switch is on. Reason : The drift velocity of electrons in a metallic wire is vary high.

Assertion : An electric bulb becomes dim, when an electric heater in parallel circuit is switched on. Reason : Dimness decreases after sometime.

Why an electric bulb becomes dim when an electric heater in parallel circuit is switched on? Why dimness decreases after some time?

The internal construction of an electric bell is shown in the given figure. The switch is in OFF position. When it is switched ON, one part of the bell moves. The part that moves when the switch is closed is the
