What does the capacitance of a capacitor affect

Are too high capacitance capacitors "bad" for the circuit?

But large capacitors can affect the stability of op-amps or switching regulators. And they can give rise to large inrush currents when power is first connected to a circuit. Even if the inrush can be accommodated, it may cause the power source Voltage to droop, and if other circuitry is attached to that power source, it may reset or malfunction due to the droop.

Is there a physical explanation for why increasing a capacitor''s

This means that a capacitor with a larger capacitance can store more charge than a capacitor with smaller capacitance, for a fixed voltage across the capacitor leads. The voltage across a capacitor leads is very analogous to water pressure in a pipe, as higher voltage leads to a higher flow rate of electrons (electric current) in a wire for a given electrical

Why does the area of the plates affect the capacitance?

capacitor is fixed for particular size of capacitor. greater the size of capacitor, greater will be its capacitance.
