Project-1:

    How to make a 9VDC source from 220 V AC system by using bridge rectifier circuit. 

              A bridge rectifier is an arrangement of four or more diodes in a bridge circuit configuration which provides the same output polarity for either input polarity. It is used for converting an alternating current (AC) input into a direct current (DC) output. A bridge rectifier provides full-wave rectification from a two-wire AC input, therefore resulting in lower weight and cost.

     A bridge rectifier circuit given here,
                                                     

BRIDGE RECTIFIER

LM 7809 IC description means where input and where output you connect given in the figure below,

In this video i describe how one can make a 9 VDC source from our domestic 220 VAC source.I use basically a transformer,a bridge rectifier circuit and a voltage regulator.
