Consider the circuit given below where A, B and C are three identical light bulbs of constant resistance.


(a) List the bulbs in order of increasing brightness.


(b) If C burns out, what will be the brightness of A now compared with before?


(c) If B burns out instead, what will be the brightness of A and C compared with before?

(a) Here A and B are connected in series so the brightness of the A and B will same while C are connected in parallel so the brightness of the bulb C is maximum.

(b) Their will be no effect on A and B.


(c) A and B are connected in series so if B burns than A also not glow but their will be no effect on C, as C is connected in parallel.
