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

1.	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» 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.

(i) The current in A

, A

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

will be zero as the BULB is fused and the circuit breaks at that POINT.
