INSTRUCTION

  1. Connect the components as mentioned below:
    L1-L3, L4-L7, L8-L15, L15-L10, L11-L17, L16-L18, L17-L5, L18-L6, L13-L15, L14-L19, L9-L16, L12-L9.(For eg. click on 1 and then drag to 3 and so on.)
  2. Click on 'Check Connection' button to check the connections.
  3. If connected wrong, double click on the wrong connection. Else click on 'Delete all connection' button to erase all the connections.
  4. Set DC voltage to 6 volt.
  5. Set the Series Resistance (RS) to 100 Ω
  6. Set Zener voltage (VZ) to 5.1 V.
  7. Vary the Load Resistance (RL).
  8. Voltmeter is placed parallel to load resistor and ammeter series with the series resistor.
  9. Choose Load Resistance in such a manner, such that the Zener diode is 'on'.
  10. Now note the Voltmeter and Ammeter reading for various Load Resistance.
  11. Increase the load resistance (RL).
  12. Note the Load current(IL), zener current(IZ), Output voltage(VO)
  13. Calculate the voltage regulation.
  14. Repeat the experiment VZ =10 v, RS= 100 Ω, DC voltage = 12 v, vary Load Resistance.
