What happens to the reading of A1 , A2 , A3 and A when the bulb B2 gets fused?

Solution:

In a parallel circuit, the potential difference does not become divided. As a result, when bulb one is fused, the glowing of the other bulbs will not be affected.

3 Amperes are being measured by Ammeter A. In other words, the Al, A2, and A3 all show evidence of IA reading.
