If there are two bulbs connected in series and one blows out, what happens to the other bulb?

(a) The other bulb continues to glow with the same brightness

(b) The other bulb stops glowing

(c) The other bulb glows with increased brightness

(d) The other bulb also burns out

I got this question in semester exam.

I'm obligated to ask this question of Series Circuits in section Simple DC Networks of Basic Electrical Engineering

Best answer
Right choice is (b) The other bulb stops glowing

For explanation: Since the two bulbs are connected in series, if the first bulb burns out there is a break in the circuit and hence the second bulb does not glow.
