![2.___[10 pts ] A lightbulb is connected to a battery as shown. What happens to the current after it passes through the bulb?](http://img.homeworklib.com/questions/a49f27c0-4d62-11eb-8c22-33e1c7d764ef.png?x-oss-process=image/resize,w_560)
Homework Answers
Current is just the flow of the electrons.
As per charge conservation rule charge is neither gererated or consumed in the blub as the is no chemical reaction taking place in the blub
This is also called Kirchoff's current law.
So the current stays the same.
