The input and output of the capacitor filter show the change in the waveform. Capacitors used for this purpose are electrolytic types because large capacitances are needed in a limited space. Common values for the capacitors range from 4 to 2000 microfarads. Working voltages of capacitors should be in excess of the peak voltage from the rectifier.
The coil is an inductor and is measured in the unit Henry (H). A simple coil consists of an iron core wrapped with the copper wire. If a DC voltage is applied to a coil, the current flows through the coil and only builds up a magnetic field there. To put it simply: the current flowing into the coil takes some time until it flows out of the coil ...
