CONTROLS

  Select Diode:

  Rh : ohms


INSTRUCTION

  1. Select the diode
  2. Set the rheostat Rh=1 Ω
  3. By adjusting the rheostat, voltmeter reading is increased from 0 and in each time note the corresponding reading in milliammeter.
  4. Take the readings and note Voltmeter reading across Zener diode and Ammeter reading.
  5. Plot the V-I graph and observe the change.
