Question.4754 - Pre-Lab QuestionsWould a 500 μF or 100 μF capacitor keep a light bulb on longer? Explain your reasoning.How much charge can a 100 μF capacitor store if it is connected to a 10 V battery? How does this compare to the charge stored when it is connected to a 20 V battery?How long would the sides of plates need to be if you were to construct a 1 F parallel plate capacitor using square plates that were separated by 2 millimeters?Why do you get a larger capacitance with capacitors in parallel and a smaller capacitance for capacitors in series?Calculate the capacitance of a 500 μF and 100 μF capacitor in series and parallel. Rank the four capacitances from greatest to smallest (the individual capacitors and their capacitance in series and parallel).Experiment 1: capacitors in series and parallelData SheetTable 1: Snap Circuits Capacitance DataTrialCapacitance 1 Time (s)Capacitance 2 Time (s)Capacitance 3 Time (s)Capacitance 4 Time (s)1 2 3 4 5 6 7 8 9 10 AveragePost-Lab QuestionsHow did the behavior of the LED differ when you added the second capacitor in Part 1?After adding the 100 μF capacitor in Part 1, are the capacitors in series or in parallel? Use data to support your answer. Calculate the equivalent capacitance.How did the behavior of the LED differ when you added the second capacitor in Part 2?After adding the 470 μF capacitor in Part 2, are the capacitors in series or in parallel? Use data to support your answer. Calculate the equivalent capacitance.The longer the light bulb is lit, the larger the capacitance. Calculate the capacitance for each circuit arrangement. Rank your capacitances in order from greatest to least based off of the average time the light bulb was lit. Does your ranking agree with your calculations?
