Question

1.         If you had to produce a capacitor of 1000 µF using a vacuum gap of 0.100 mm (thickness of paper), how would the area needed compare to a football field? Given this enormous size, how do modern commercial capacitors get around this problem.

2.         Prove the RC has units of seconds.

3.         A statically charged balloon holds about 5 x 10^-8 Coulombs of charge. How many “balloon worths” of charge is store in a 1000 µF at 6.00 V?

4.         Explain why the measured voltage across each individual capacitor in series varies inversely with its capacitance.

5.         Why does a charged capacitor’s voltage reduce briefly when place in parallel with an initially discharged capacitor?
