Question

In the given circuit, B1, B2 and B; are three bulbs connected with a battery of 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:

(i) The current in A

1

, A

3

will increase and in A it will be greatest as it is the total of the current flowing through the circuit.

The current in A

2

will be zero as the bulb is fused and the circuit breaks at that point.
