How does the filter capacitor work

How filter capacitors work is based on the principle of capacitive reactance. Capacitive reactance is how the impedance (or resistance) of a capacitor changes in regard to the frequency of the signal passing through it. Resistors are nonreactive devices. This means that resistors offer the same resistance to a signal, regardless of the signal''s ...

How does a filter capacitor work?

The circuit diagram of the filter capacitor is shown below. In this circuit, the capacitor works like a high pass filter that allows high frequencies and blocks direct current. Similarly, they can also work as a low pass filte r to allow DC and block AC. Here the capacitor is connected in parallel with the component instead of connecting in series.
