Question 1

Current I flows into three resistors that are connected together one after the other, as shown in the top figure, below. The graph below shows the relative value of the potential across each resistor as a function of position.

1. [1 point] Rank, in order from largest to smallest, the three resistance values R1,R2,R3.
2. [2 points] Briefly explain your answer to Part A. An answer consisting of just "Ohm's law" is not an explanation - it's just the name of a physical law - and will not receive any points.

Question 2: The circuit diagram below shows five identical lightbulbs connected to each other and a battery; all the bulbs are all glowing, and all circuit elements are ideal.

1. Rank the brightness of the bulbs, from brightest to dimmest.
2. Briefly explain your reasoning for Part A. An answer consisting of just "Ohm's law" is not an explanation - it's just the name of a physical law - and will not receive any points.
