shunt or parallel clipper parallel negative clipper In this parallel negative clipper and positive clipper difference between the diode orientation in this paralle negative clipper have a diode and one resistance and another one is load resistance During positive half cycle the diode becomes reverse biased and entire current will flow through the load resistance When the diode is reverse biased the diode act as oprn switch or loop no current flows through the diode During negative half cycle the diode will be forward biased and entire curent will flow through the diode When the diode is forward biased and the diode act as a close switch or loop the entire current will flow through the diode input and output waveforms click here to follow me in instagram instagram

positive clipper shunt positive clipper The basic shunt clipper the diode is connected is parallel with the load resistance During positive half cylce the diode becomes forward biased and the diode act as a closed loop. The entirely current flows across the diode Ouput across the load resistanc is zero voltage During negative half cycle diode becomes reverse biased the diode act as a open loop The negative half cycle the entire negative ouput will be across the load resistance Input and output waveforms click here to fallow me in instagram instagram

Negative Clipper Series Negative Clipper "The circuit which is use to clip off (unwanted) portion of the wave forms without disterbing remaining part of the waveforms" circuit diagram In negative clipper only conduct positive waveforms nad clip off the negative waveforms when positive cycle of wave form the diode will be forward biased and entire current will through load resistance when negative half of the cycle the diode will be revere biased and there no conduction through the diode input waveforms is output waveforms is instagram

Intruduction of Clipper Circuits Clipper Circuits Clippes circuits are use to clipoff(remove) a unwanted frequency singnal from wavforms. there are four type of clipper circuits Series positive clipper series negative clipper shunt positive clipper shunt negative clipper series positive clipper Today we are going to understand series positive clipper Series Positive clipper is a electronic circuit which removes positive of the wave forms when positive half cycle of wave for diode will be reverse biased ther is no current flow between terminals. negative half cycle diode will be forward biased and and current will flow between the load and neagative half cycle only flow the input wave form is the output waveforms is This is ...

PN JUNCTION: Formation :- The N and P-type semiconductors are basic building blocks for semiconductor devices. Joining of N-materials and P- materials type semiconductor forms a PN junction which is importance in electronic systems.         PN Junction formed by doping of N-type impurity and P-type impurity side by side in a single piece of semiconductor. And it’s called PN Junction diode Inner of diode

ELECTRICITY 1) Charge is a fundamental particle in an account in an atom.It may be positive or negative. 2) Like charges repel each other. 3) Unlike charges attract each other.       Coulomb(C ) :S.I.unit of charge      1 Coulomb = Charge present an approx.6*10 to the power of 18 electrons 4) Charge on 1 electron = Negative charge of 1.6*10 per C                                                      Q = ne Where     Q = Charge(total)                 n = No. of electrons                 e = Charge on one electron Current(I):   the rate of flow of charge is called current.                               ...
