Zener Diode As Voltage Regulator

in a zener diode (dc voltage regulator) circuit with V_("zener")=7.0 V is used for regulation. Thhe load current is to be 4.0 mA and te unregulated input is 11.0 V. what should be te value of series resistor R_(s) if zener diode current is five times te load current

A certain p-n junction, having a depletion region of width 20 mum , was found to have a breakdown voltage of 100 V. If the width of the depletion region is reduced to 1 mu m during its production, then it can be used as a Zener diode for voltage regulation of

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

A Zener diode

Draw the I-V characteristics of a zener diode also sketch the circuit diagram of zenre dioode as a voltage regulator

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

A Zener diode when used as a voltage regulator is connected (a) in forward bias (b) in reverse bias ( c) in parallel to the load (d) in series to the load.
