"WebbCapacitors oppose voltage change by creating current in the circuit: that is, they either charge or discharge in response to a change in the applied voltage. So, the more capacitance a capacitor has, the greater its charge or discharge current will be for any given rate of voltage change across it. The equation for this is quite simple: " - The purpose of op amp comparator is to
