Chapter 6.2, Problem 3cT

Both circuits al right have more than one path for the current. Sketch all possible current loops on the diagrams. (A “current loop” is a single path of conductors that connects one side of the battery to the other.)

For each of the current loops you have drawn, calculate the sum of the potential differences across the bulbs in that loop. (Use the measurements you made above.)

How do the sums of the potential differences across the bulbs in each loop compare to the potential difference across the battery?
