Capacitor filtering formula

The working of this capacitor mainly depends on the capacitive reactance principle. It is nothing but how the impedance of a capacitor alters with a signal frequency that is flowing through it. A nonreactive component like a resistoroffers similar resistance to a signal apart from the frequency of the signal. This means 1Hz &.
