Understanding Current in a Parallel Circuit with Multiple Light Bulbs

Sal connected four light bulbs in a parallel circuit. If Sal adds another light bulb, what is true about the current in each bulb?

A) The current decreased when a fourth bulb was added.

B) The current in the four bulbs is much less than the current in three bulbs.

C) The current in each bulb remained the same even though another bulb was added.

D) The current in the fourth bulb is less than the current in the other three bulbs.

What is true about the current in each bulb when Sal adds another light bulb?

The current in each bulb remained the same even though another bulb was added.

Since all the bulbs are connected in parallel with each other, the voltage across each bulb will remain the same. Therefore, the current in each bulb will also remain the same, as determined by the equation I = V/R. Since all the bulbs are identical and have the same voltage source across them, the current in each bulb will stay constant.
