Two capacitors are connected in series.
(a) If a third capacitor is now connected in series with the original two, does the equivalent capacitance increase, decrease, or
remain the same? (b) Choose the best explanation from among
the following:
I. Adding a capacitor generally tends to increase the capacitance, but putting it in series tends to decrease the capacitance; therefore, the net result is no change.
II. Adding a capacitor in series will increase the total amount
of charge stored, and hence increase the equivalent
capacitance.
III. Adding a capacitor in series decreases the equivalent capacitance since each capacitor now has less voltage across it, and
hence stores less charge
