If I add more light bulbs in series to a circuit that originally only had one lightbulb, what happens? (HARD question-read carefully)
|
|
The current increases and the original lightbulb gets brighter
|
|
|
The current diminishes and the original lightbulb dims

Explanation:
Detailed explanation-1: -In a series circuit, as more bulbs are added, the brightness of each bulb decreases. This is because the resistance R increases which causes the current I through each bulb to decrease (recall I = V/R).
Detailed explanation-2: -The same current flows through each part of a series circuit. If the circuit is broken at any point, the circuit would be open and no current will flow. So, if one of the bulbs blows out, the other bulbs would not be able to glow.
