Answer:

When bulb B1 gets fused, the currents in B2 and .B3 remain same I2 = I3 = 1A, so their glow remains unaffected.

Answer:

Explanation:

the current in A1 and A3 will increase                              

and in A there will be the greatest flow of current  

the current in A2 will be zero              as the bulb is fused

the cuircuit will break

Current in ammeter A1 = 1 A

Current in ammeter A2 = 0

Current in ammeter A3 = 1 A

Current in ammeter A4 = 2A

Explanation:

(i) When bulb B1 will get fused, the currents in B2 and B3 are still same I2 = I3 = 1A.

Therefore, the glow of these bulbs will not be affected

(ii) When bulb B2 gets fused, the current in .B2 turns to be zero and currents in B1 and B3 remains 1 A.

therefore, Total current I = I1 + I2 + I3

= I + 0 + I = 2A

Current in ammeter A1 = 1 A

Current in ammeter A2 = 0

Current in ammeter A3 = 1 A

Current in ammeter A4 = 2A
