ZENER DIODE AS VOLTAGE REGULATOR

(i) What is Zener diode? (ii) Explain with circuit diagram how a Zener diode regulates voltage across a load resistance.

Assertion (A): Zener diode is used as a voltage regulator. Reason (R ): Zener diode operated in reverse biased condition.

A car stereo working at stabilized voltage supply of 9V DC and has a Zener diode of 9V , 0.25 W . But the voltage supply inside the car is 12 V DC . The boy approached you to get help . a. Which mode of bias will you suggest to connect Zener diode as voltage regulator ? b. Draw a circuit diagram of voltage regulation to help the boy . c . Which device is essential for circuit diagram ? Find the value of that device . [ Hint . Current through the load , I_(L) = 0 ]

What is breakdown voltage of a Zener diode? Explain its use as a voltage regulator.

A zener diode voltage regulator operated in the range 120-180V produces a constant supply of 110V and 250mA. To the load.If the maximum current is to be equally shared between the load and the zener, then the values of series resistance (R_(s)) and load resistance (R_(L)) are

The breakdown voltage of a zener diode is V_(Z) . It is connected to the supply of V volts, so which of the following options for diode will act as regulated voltage?
