6 V.

(a) What will happen to the glow of the other two bulbs if the bulb B2,

gets fused?

(b) If the wattage of each bulb is 3 W, what reading will ammeter A show

when all the three bulbs glow simultaneously.

(c) Find the total resistance of the circuit.​

Answer 1

Answer:

Study the circuit shown in which three identical bulbs B1, B2 and B3 are connected in parallel with a

battery of 4.5V.

(i) What will happen to the glow of other two bulbs if the bulb B3 gets fused ?

(ii) If the wattage of each bulb is 1.5 W, how much reading will the ammeter A show when all the three bulbs glow simultaneously.

(iii) Find the total resistance of the circuit.
