There are 4 diagrams for this questions. Which one do you think it's true?
(The diagram has a battery with a lightbulb attached to it)
The Attempt at a Solution
I think that the current flows from one end to other end but not sure if the current gets weaker or current stays the same.
I am thinking that the current gets weaker due to the current used to light the lightbulb, which I think it's the way to calculate the voltage.
