diode is a unidirectional component,it allows passing a
signal in one direction and blocks it in another
direction.when it is forward biased it allows the signal to
pass through it and it blocks that signal if it is reversed
biased.it is used as a switch
it is similar to the water pipe having a volve which allows
water in only one direction. When water is flowing towards
the other direction, the water is blocked by the volve. The
diode is working like this.
dode is an electronic device which is the combination of p
and ntype semiconductors.due to this a potential barrier is
formed and this will not allow current when the diode is
reverse biased due to the extension of potential
barrier.diode allows current in farward biased mod due to
the minimised potential barrier.so it isused to convert a.c
supply to d.c supply.
i am also applied for the AAI jr
executive (electronics/ATC) written test.
pls forward me the syllabus & test pattern if any question
any one got reply for this quaries?
if any one know plz reply to me on my email
we r saying that low pass rc filter will allow low frequency
components n attenuates the high frequency components..but
at low frequency reactance offer by capacitor is high..it
will act as open circuit..hence there will no output..but
practically we getting output. how?
