Why diode don't allow the current coming in opposite direction?

Diode is known as a rectifier because it only allows the current to flow in one direction. Diode is only effective when the input is AC.

What is zeren diode?
A normal diode only allows current to flow in one direction, e.g: A to B. However, current will only flow across this diode A to B when there is a voltage ( called the breakdown voltage), and different normal diodes require different voltages to allow current to flow, e.g: silicon diodes allow current to flow A to B when there is a minimum of 0.6V flowing, at which point the resistance drops, and current flows. A zener diode does exactly this, however, it also allows current to flow in an opposite direction once the breakdown voltage for this direction has been reached. e.g: if a Zener diode has a breakdown voltage of 3.6V, at 3.6V its resistance will drop significantly enough so that current can flow. hopes this helps
What is the working principle of a diode?
Diodes allow electricity to only flow in one direction, thus converting alternating current (a.c.) into direct current (d.c.). They also allow electrons to flow one way only (until reverse breakdown occurs - then current may flow in both directions). Diodes are often used in both domestic and industrial applications and they are especially useful in electrical circuits.
What is meant by unilateral and bilateral circuits?
if a network is having both sides voltage and current sources; and if the direction is changed from any side there will be no change in circuit characteristics. so it is called bilateral network.
Did capacitor allow change in current?
capacitors allow ac current to flow.
Does a Cpacitor allow ac to pass through it?
no capacitor does not allow ac component .if allow then inductor allow dc component .
What is the purpose is of a diode?
The purpose of a diode is to allow electric current to pass in one direction while blocking electric current in the opposite direction. It is for this reason that diode is usually referred as the check valve.
Can you install a diode to allow 24 volts AC to flow in one direction but not allow the flow of 24 volts AC to flow in the opposite direction?
Diodes convert AC into DC by allowing current flow in one direction only. Since AC is alternating between plus and minus it is not possible to use a diode to allow AC to flow in one direction and not in the other direction.
What is zenor and zener diode?
Zenor diode is allow to flow current in forward direction and it can also allow current in reverse direction when the voltage is above the certain value.
How the current flow through npn?
A; The base must be positive with respect to the emitter this condition will allow collector current to flow from collector to emitter. If the transistor manage to get saturated the current can flow in both direction. as a switch
What is a function of a transistor?
To allow current to flow in only one direction.
What is the function of ratchet handle?
to allow linear or rotary motion in one direction while preventing motion in opposite direction
What is the uses of semi conductors diodes?
allow current to flow in one direction
Why use diode in a circuit?
They only allow current to flow in one direction.
What is forward bias current in semiconductor?
I think its related to junction of two dissimilar semiconductor (or semiconductor and metal) and not only a semiconductor. well when two opposite nature semiconductor (hetero or homo) are joined to form a junctions they allow the flow of current in one direction while blocks it in other direction. The applied bias V which will cause the current flow is called forward bias and the current flowing through the junction forward bias current.
What is zeren diode?
A normal diode only allows current to flow in one direction, e.g: A to B.

What is difference between diode and led?
They both only allow current in one direction, but the LED emits light when current is flowing.
Why diode is called mechanical valve?
A valve allows flow in only one direction. Diodes allow electrical current to flow in one direction only.
