If you have 3 capacitators, how many combinations of capacitance can you produce?
You are to connect capacitances C1 and C2, with C1 > C2, toa battery, first individually, then in series, and then in parallel.Rank those arrangements according to the amount of chargestored, greatest first.
Consider two long, parallel, and oppositely charged wires of radius r with their centers separated by a distance D that is much larger than r. Assuming the charge is distributed uniformly on the surface of each wire, show that the capacitance per unit length of this pair of wires is (C)/(ℓ) = (π∈0)/(ln (D/r))
