Question

The circuit shows a battery and 4 lamps. All lamps are lit. One lamp fails and all the lamps go out. Which lamp failed?

Answer 1

As per the question,

It is referring some image, but is not in the attachment.

As per the question, there is 4 electric lamps are connected, initially all the lamps was glowing,

But as per the question, any one lamp fails, then all the lamps are stop to glow, it means all the lamps are connected in series, when any one lamp, fails in the series connection, then all the lamp will stop to glow because the flow of the current will get interrupted, and it is difficult to find that which one has been failed, we have to check each and every bulb.
