Diodes, AC supply, Resistor, CRO, Capacitor

First of all I connected the four diodes in a bridge mechanism and connected the bridge with the AC supply and with the resistor and it was further connected with the capacitor which acted as a filter to remove the ripple factor. During the +ve half cycle the diodes D1 & D3 become forward biased and during the –ve half cycle diodes D2& D4 become forward biased as shown in the fig. while the capacitor remove the ripple from the output DC to make it pure.

In the experiment, we have used capacitor. A capacitor is a device which stores charge in it.

It is time taken by a capacitor to store 0.63% of the total charge stored in it.

RC=t

It is capacity of capacitor to store charge in it and charging is directly proportional to applied voltage.

Q=CV

Where C is the capacitance of the capacitor and it is measured in Faraday.

During the +ve half cycle the capacitor become charged and in the –ve half cycle, it uses the charge.
