Are too high capacitance capacitors "bad" for the circuit?
Take for example a fat car battery supplying your circuit with 12V through 1mm^2 copper wires. Suppose that the input of your circuit has a 100,000 microFarads of big fat capacitor there, what length of supply wire would be less than 0.05 ohms so go to 120 Amps when first connected? Don''t try that at home. To design a circuit which is safe and
