Answer / anum ahmed pirkani
p region has holes as majority charge carriers and n region has electrons as majority charge carriers
in case of forward biasing when the potential of battery is greater then that of depletion region, the positive end of battery repels the holes of p-region and negetive end of battery repels the electrons of n-region this thereby decreases the width of depletion region thereby allowing more current to pass.
in case of reverse biasing, the negetive end of battery attracts the holes of p-region and the positive end of battery attracts the electrons of n-region. in this way, the majority charge carriers of both regions are attracted to the battery thereby increasing the width of depletion region and offers more and more resistance to the flow of current as voltage increases and ultimately breaks down the diode.

Answer / karuna
diode is electronic components .it is used to
forward&reverse bias .it is carring the current in forward
bias in holes and reverse bias it contains electrons.it is
a.pn diode.it emits the signal into the electricalsignals.

Answer / shrikul joshi
All ^ the question is what is the principle on which diode
works not the uses of diode....Diode works on principle of
diffusion and drift currents.
Although diode allows unidirectional passing of current it
is a biplor device because conduction is due to both holes
and electrons

Answer / yogesh kumar
Working of diode is based on the principle that it allows
flow of current when forward biased and restrict the flow
of current when reversed biased.

Answer / r.ravibharathi
diode is an electronic device which consists of two
electrodes in which current is unidirectional and it flows
from anode to cathode ,the flow of current is restricted
when it is reverse biased i.e,when cathode is connected to
positive and the anode is connected to negative.there is a
flow of current when the diode is forward biased,hence it is
unidirectional circuit element.

Answer / vignesh.a
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.

Answer / achalla vijayshree
If a junction is formed between n type and p type doped
semiconductors, the conduction along the junction has a
strongly unidirectional property. In other words, it
conducts current in one direction (when it is forward
biased) and hardly conducts any current in the other
direction(when it is reverse bised). Such a junction device
is called semiconductor diode. Diode has got current
control property and is extensively used in electronic
devices.

Answer / pratibha
In electronics, a diode is a two-terminal P-N junction
device .The most common function of a diode is to allow an
electric current in one direction (called the forward biased
condition) and to block the current in the opposite
direction (the reverse biased condition).

Answer / sachin saini
diode as a switch unidirectional current flow property of a
diode makes it suitable for use as an electronic switch.
