Explain why the bulb would not glow in the arrangement shown in Fig. 12.13.


Answer :

(1) The bulb would not glow in the arrangement because the circuit is not complete due to the presence of an insulator in the centre.

(2) A bad conductor or insulator does not allow to pass the electric current.

(3) So we can say that the circuit is open, and the bulb will not glow.
