The answer says the equivalent capacitance is always less than C1 but I can’t come up with thy. When I do this, I can’t seem to prove that equivalent capacitance is always less than C1. For example, if I let:
C1 = 998 F, C2 = 999 F, C3 = 1000 F and C4 = 10001 F, then I get an answer (767119326 F) and this is much larger than C1. Any suggestions?
(I realize the capacitances used here are very large, but they are just used to make a point.)
