Description : How much time a diode takes to switch ON in forward bias condition.
Answer : t=0 sec.
Description : What is the difference between forward and reverse bias?
Answer : Forward bias is a PN junction bias which allows current to flow through the junction. Forward bias decreases the resistance of the depletion layer. Reverse bias is a PN junction bias that allows only ... Positive polarity on the n-type material and negative polarity to the p-type material.
Description : Can we use a zener diode as a rectifier?
Answer : Yes we can use zener diode as rectifier but it have limitations better to use normal diode. Zener diode have some different applications.
Answer : PN junction of zener diode is heavily doped than ordinary diode. For the occurrence of Zener effect the zener diode is heavily doped. If the zener diode is not heavily doped then Zener effect ... breakdown voltage is sharp. If the diode is lightly doped the diode will have higher breakdown voltage.
Answer : Yes dynamic impedance of zener diode vary.
