a.what happens to the glow of other two bulbs?
b. what happens to the reading of A1,A2,A3 and A when bulb B2 gets fused?
c. how much power is dissipated in the circuit when all three bulbs glow together?

IF THE THREE BULBS ARE IN SERIES :
aa) The glowing of the bulb depends upon the energy dissipated per second which is power (= V2/R). Since after B1 fuses then the current flow will break and all other bulbs will also not glow.
bb) The current in A1,A3 and A will increase while the current in A2 it will zero.
IF THE BULBS ARE IN PARALLEL :
aa) There will be no change in the glow of the bulb since, both V and R will not change for the bulbs.
bb) The current in A1,A3 will increase and in A it will be greatest, the current in A2 will be zero.
