`B_1,B_2 and B_3` are three identical bulbs connected as shown in (fig. 3.46). When all the three bulbs glow, a current of `3 A` is recorded by the ammeter `A`.
(i) What happens to the glow of the other two bulbs when the bulb `B_1` gets fused ?
(ii) What happens to the readings of `A_1,A_2,A_3 and A` when the bulb `B_2` gets fused ?
(iii) How much power is dissipated in the circuit when all the three bulbs glow together ?
