1

CONTROLS

  Select Diode: VR
   DC volt :       Volt
   Resistance :   ohms

INSTRUCTION

  1. Connect the components as mentioned below:
    L1-L3, L4-L7, L8-L10, L5-L10, L6-L11,L9-L11, L9-L12.(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 0.2 V .
  5. Set the resistor and select diode.
  6. Voltmeter is placed parallel to diode and ammeter series with resistor.
  7. The positive of battery to the N side(cathode) and the negative of battery to the P side(anode) of a diode.
  8. Now vary the voltage upto 30V and note the Voltmeter and Ammeter reading for DC voltage .
  9. Take the readings and note Voltmeter reading across Silicon diode and Ammeter reading.
  10. Plot the V-I graph and observe the change.
