Description : Draw symbols of zener diode and LED.

Answer : Symbol of zener diode : Symbol of LED

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 : 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 : 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 ?

Description : State any two applications of zener diode.

Answer : Applications of Zener Diode: i) As a voltage regulator. ii) As a fixed reference voltage provider in transistor biasing circuits. iii) As peak clippers or limiters in wave shaping circuits.
