How does a filter circuit work?

The filter is a device that allows passing the dc component of the load and blocks the ac component of the rectifier output. Thus the output of the filter circuit will be a steady dc voltage. The filter circuit can be constructed by the combination of components like capacitors, resistors, and inductors.

Why do people attach filter to their faucets in at home?

A water filter is a device that's usually attached to your faucet or water supply that filters out unwanted sediment and minerals from your tap water. ...
