1. The problem statement, all variables and given/known data 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) 2. Relevant equations N/A 3. 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.
