Answer 2

Answer:

1. the glow of the bulbs B2 and B3 will remain the same as the V and R remains the same.

2. When bulb 2 gets fused:

 Reading on A1 is 1 ampere, reading on A2 is 0 ampere, reading on A3 1  ampere and reading on A is 2 ampere.

3. Assuming the voltage being V the resistance of the circuit is:

 R=V/I=V/3
