Why do we get current in reverse bias?
because semiconductor diodes are not perfect insulators when reverse biased. if you want a diode that is a perfect insulator when reverse biased, use a vacuum tube diode.
Why diode use in parallel?
1. Redundancy: If one diode breaks (in a way that makes it an insulator), the other diode(s) will do the job. In case of that kind of diode breakage the circuit is like an OR-gate: If diode1 OR diode2 OR ... OR diodeN works properly, then the circuit works properly. If it is important to make sure that the diode does not wrongly conduct, then the diodes should be in series. 2. Reducing the forward voltage: In power electronics high currents need to be conducted with parts that are as ideal as possible (concordantly in this case each diode should be able to carry at least the full current, that has to be transferred through the group of diodes, in order to avoid a cascaded cataclysmic thermal runaway due to a decrease of the forward voltage of the overheated diode).
How is zener diode different from a conventional diode or ideal diode?
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
What is Zener resistance of the Zener diode?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
Is a diode an insulator?
No. A diode conducts in one direction but not in the other.
Can a diode act as a source of emf?
NO
What is the disadvantage and advantage of photo diode and transistor?
photo diode donot work for long distance photo diode act as a receiver
Why do we get current in reverse bias?
because semiconductor diodes are not perfect insulators when reverse biased. if you want a diode that is a perfect insulator when reverse biased, use a vacuum tube diode.
Is a toothpick a conductor or a insulator?
If the toothpick is made of wood or plastic, it would act as an insulator.
What are defense?
mechanics that act as an insulator or condutor
Is diode an active device?
A passive device is a diode resistor coil and so forth it perform no enhancement to the circuit or act on it.
Why does alcohol act as an insulator?
Alcohol acts as an insulator because it can't freeze and its ability to absorb energy.
What is diote?
A diode is semiconductor device which is used in a lot of application in electronics equipment.it is negative temp. coefficient device i.e. at lower temp. it is behave like a insulator and high temp. it is work like a good conductor. Basically a diode is used to convert an alternating current into direct current in form of a rectifier. There are many types of diode used in today day to day life depends upon their application. 1 crystal diode 2 photo diode 3zener diode are some of the most useful diode.

What are defense mechanism?
Hiding
What objects act like a conductor and insulator?
The substances which have free electrons(which move freely ) act as conductor while those whose electrons held tightly (which can not move freely) are insulator.
