Why does the light go out? O The existence of two paths reduces the current through the bulb in half O The wire causing the short circuit has much less electric resistance than the light bulb, so the voltage stays the same with much less current through the bulb than through the short circuit wire. The current almost entirely through the added wine because of its very low resistance, and the voltage also drops rastaly O The voltage drops drastically but the resistance across the circuit does not change °The existence of two paths reduces the voltage across the bulb in half 10/30/2017 Type here to search

Explanation / Answer

The current will always take the easiest path that is available to it, means that it'll try to take that path where there is least resistance. Here, there are two paths available to flow from the lower end to the upper end- the right path where the current has to go through the bulb (which creates hurdle/resistance) and the left path where its free to move without any such hurdle.

Hence, most of the current will just flow through the left path and not through the right path, so bulb will not glow as long as the left circuit is in place.The correct answer will be the second option here.
