Description : Can we use a zener diode as a rectifier?
Last Answer : Yes we can use zener diode as rectifier but it have limitations better to use normal diode. Zener diode have some different applications.
Last 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.
Last Answer : Yes it can be, and it will act like a normal PN junction diode. The characteristic of ZENER diode is exactly same as PN junction diode in forward Bias.
Description : Draw symbols of zener diode and LED.
Last Answer : Symbol of zener diode : Symbol of LED
Description : While studying the V-I characteristics of a zener diode, there are two different values of resistors connected in series with it. In case of the forward characteristics, a ~70 ohm resistor is connected ... ~510 ohm resistor. What is the reason behind it ? Is the difference really necessary ?
