What happens to the current supplied by the battery when you add an identical bulb in parallel to the original bulb?

a. The current is cut in half.
b. The current stays the same.
c. The current becomes zero.
d. The current doubles.

b. The current stays the same.

Explanation:

In the case given current is supplied by the battery to a bulb . Here, we should know that bulb also apply resistance to the flow of current .

Now, when an identical bulb is connected in parallel to the original bulb .

Therefore, both the resistance( bulb) are in parallel.

We know, when two resistance are in parallel , current through them is same and voltage is divided between them.

Therefore, in this case current stays same in the original bulb.

Hence, this is the required solution.

the answer for apex is the lowest
