$B_{1}$, $B_{2}$ and $B_{3}$ are three identical bulbs connected as shown in figure. Ammeters $A_{1}$, $A_{2}$ and $A_{3}$ connected as shown. When all the bulbs glow, the current of 3 A is recorded by ammeter A.

(i) What happens to the glow of the other two bulbs when bulb $B_{1}$ gets fused?
(ii) What happens to the reading of $A_{1}$, $A_{2}$ and $A_{3}$ 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?
