128. B1,B2 and B3 are three identical bulbs connected as shown in figure. Ammeters A1, A2 and A3 are connected as shown. When all the bulbs glow, the current of 3 A is recorded by ammeter A. (a) What happens to the glow of the other two bulbs when bulb B1 gets fused? (b) What happens to the reading of A1, A2, A3 and A when the bulb B2 gets fused? (c) How much power is dissipated in the circuit when all the three bulbs Glow together?
