Keep all the resistances (\(R_1\), \(R_2\), \(R_3\) & \(R_L\)) close to their respective maximum values. Choose any arbitrary values of \(V_1\) and \(V_2\).

Experiment Part Select:

Case 1:
Select switch of \(S_1\) to Power and \(S_2\) to Load and Simulate the program from Case 1 tab. Observe the result of load current.

Case 2:
a)Norton Short circuit current analysis:
Apply switch \(S_1\) to power and \(S_2\) to Short and Simulate the program and read Norton short circuit current (\(I_{sc}\)) from Case 2(a) tab.

b)Norton Resistance analysis:
Apply switch \(S_1\) to short and \(S_2\) to power and Simulate the program and read Norton resistance (Rn) from Case 2(b) tab.

Case 3: Using \(I_{sc}\) and \(R_n\) determine Load Current
Simulate the program and read Load current (\(I_L\)) from Case 3 tab. Compare the load currents (\(I_L\)) obtained from Case 1 tab.
Then click the button to fill the data to the observation table.
