Question

2 bulbs one of 25w and 200w are connectedin series one bulb burnt which one burnt and why

Answer 1

Ans :- Bulb A

Ans :- Bulb A because it has low rating.

Given:-

Rating of 1 bulb = 25 w

Rating of 2 bulb = 200w

Voltage = 220 v

To find :-

Which bulb get fused and why?

Solution:-

In series arrangements the same current is flown in whole circuit.

When the two bulbs of 25 watt and 200 watt is connected in series the bulb A get fused because the current in circuit is same but the power of bulb A is less than the current flows in circuit hence, huge amount of current will flow through the bulb A and it get fused.

Bulb B doesn't fused because it's rating is high and its cam be operated .

This is the disadvantage of series arrangements and that's why households circuit is not connected in the series arrangements.
