            FULL WAVE RECTIFIER              Junction    diode  as full wave rectifier Junction diode as a full wave rectifier. A full wave rectifier consists of a transformer, two junction diodes D1 and D2 and a load  resistance R1. The input a.c. signal is fed to the primary coil P of the transformer. The two ends A and B of the secondary S are connected to the p-ends of the two diodes D1 and D2 . The secondary is tapped at its central point T which is connected to the n ends of the two diodes through the load resistance Rl . working At any instant, the voltages at the end A (input of D1) and end B (input of D2) of the secondary  with respect to  the centre tap T will be out of phase of a.c. input, and the end A is positive and the end B is negative with respect to the centre tap T. Then the along   diode  D1 gets forward biased and conducts current along the path AD1 XYTA, as indicated  by the solid arrows. The diode D2 is reverse biased and does not conduct . During the

                    RECTIFIER  Hey friends !!!  I'm back with another interesting invention in the world of electronics. Being a part of this mesmerizing world of great and unbelievable  technology ,we need to have a brief knowledge about the small parts of electronic world...... here i'll try my best to explain you about one of those inventions "THE RECTIFIER"  . Junction diode as a rectifier. Rectifier: The process of converting alternating current into direct current is called rectification and the device used for this process is called rectifier . Pr inciple of rectifier: when a p-n junction diode is forward biased , it  offers less resistance and a current flows through it ; but  when it reverse biased , it offers high resistance and almost no current flows through it.This unidirectional property of a diode enables it to be used as a rectifier .When a.c signal is fed to a diode ,the diode is forward biased during the positive half cycle and a current flows throug

Transformer                      Hey guys!!!! I am Sonal Kumari.....here to share some facts about one of the most commonly used invention in the world of electronics,  which itself serves as a part for many other circuits ......" The Transformer " . Many of the facts maybe well known to you .....so here are my efforts to give a bit more knowledge about transformer. what is a transformer!!! A Transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another , or multiple circuits. A varying current in any one coil of the transformer produces a varying magnetic flux in the transformers core ,which includes a varying electromotive force across any other coils wound around the same core. Electrical energy can be transferred between separate coils without a metallic (conductive) connection between the two circuits . Faraday's law of induction, discovered in 1831 ,describes the induced voltage effect in any coil due to a changin
