Question
The circuit at top contains an ideal battery, four identical light bulbs, and a switch. The switch is initially open. Rank the bulbs according to brightness, from brightest to dimmest, when the switch is open.Give a complete ranking using only the bulb letters and the symbols > and =.If any bulbs do not light, indicate this explicitly by setting the bulb letter equal to 0 in the ranking (e.g., W>X>Y=Z=0). Explain your reasoning

Explain your reasoningExplanation / Answer
Answer: A] When switch is open: A = B = D > C=0 All bulbs are in series in a straight line so they all have the same brightness (except for bulb C which isn't part of the completed circuit if switch is open). Hence bulb C is not even lit.
