   Zener Diode(VZ) :   Volt
   Resistance(RS) :       Ohms
   Resistance(RL) :       Ohms

INSTRUCTION

  1. Set the Zener Voltage(VZ)= 5.1 v
  2. Set the Series Resistance (RS) = 1 kΩ
  3. Set the Load Resistance (RL) = 2 kΩ
  4. Vary DC voltage from 0 to 20 v.
  5. Voltmeter is placed parallel to load resistor and ammeter series with the series resistor.
  6. Choose appropriate DC voltage such that zener diode is 'on'.
  7. Now note the Voltmeter and Ammeter reading for various DC voltage.
  8. Note the Load current(IL), zener current(IZ), Output voltage(VO)
  9. Calculate the voltage regulation.
  10. Repeat the experiment for Load Resistance (RL) = 5 kΩ
