INSTRUCTION

  1. Connect the components as mentioned below:
    L1-L3, L3-L7, L4-L5, L4-L8, L6-L9, 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 click on 'Delete all connection' button to erase all the connections.
  4. Set the Resistance Value (1 Kohm - 100 Kohm).
  5. Set DC voltage (0-30 V).
  6. Voltmeter is placed parallel to resistor and ammeter in series with resistor.
  7. Now note the Voltmeter and Ammeter reading for the DC voltage and click on 'Add to table' button.
  8. Increase the DC voltage by a factor of 2 and note Voltmeter and Ammeter Readings. Keeping resistance value constant
  9. Click on 'Plot' button to plot the V-I graph to verify Ohm's Law.
  10. V versus I graph is a straight line.
  11. Therefore from the graph we see that the resistance do adhere to Ohm’s law. Thus resistance is said to be an Ohmic device.
  12. Repeat the experiment for another set of resistance value.
