Question

B1 B2 B3 are three identical bulbs connected as shown in figure when all the three bulb flow of current of 3 ampere is required by the ammeterwhat happens to the glow of the other two bulbs and the bulb B1 get fused ​

Answer 1

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

Hope It helps you

Here is your answer

Answer 2

Answer:

you can just see the attachment is very good from the exam point of view
