Todd Floyd · Answer 1

D: When one bulb burns out, all the other lights stay on

Explanation:

In series combination of light bulbs same current must flow through all the bulbs and hence if one bulb is burn out then current through all bulbs tripped to zero and all bulbs will turn off.

Now in parallel combination all bulbs are connected parallel to the source of energy due to which the bulbs will remain in circuit if any one bulb is burn out.

So here if we used combined circuit of the bulbs i. e. parallel then in that case if one of the bulb is burn out then it must show that rest of the other bulbs must glow.

so here correct answer would be

D: When one bulb burns out, all the other lights stay on
