The circuit below shows four identical bulbs connected to an ideal battery.
Rank the bulbs in order from brightest to dimmest. If two bulbs have the same brightness, indicate that
explicitly. (Think about tracing the path of current from the battery.) Explain how you determined the
ranking of the bulbs.

When we connect a number of light bulbs in a circuit with a battery, we can use our models of current, resistance, and Kirchhoff's principles to predict the relative brightness of the bulbs. If the bulbs are all identical, then the brightness of a bulb will be an indicator of the current through that bulb (i.e., a brighter bulb has more current). A 1. The bulbs in the circuit shown on the right are all identical. Predict which bulb or bulbs will be the brightest, and which bulb or bulbs will be the dimmest. Also state if any bulbs will have equal brightnesses. Explain your prediction in detail. C All three bulbs have a resistance of 25 n, and the battery has a potential difference of 9V. 2. Determine the current through each of the bulbs. Current in bulb A = A Current in bulb B = A Current in bulb C = A 3. From your answers to part 2, do you think your prediction in part 1 was correct? Why or why not? B.
