Keep all the resistances (R1 , R2 , R3 & RL ) close to
their respective maximum values. Choose any
arbitrary values of V1 and V2 .
100
Case 1:
Select switch of S1 to Power and S2 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 S1 to power and S2 to Short and
Simulate the program and read Norton short circuit
current (Isc ) from Case 2(a) tab.
150
b)Norton Resistance analysis:
Apply switch S1 to short and S2 to power and
Simulate the program and read Norton resistance
(Rn) from Case 2(b) tab.
Case 3: Using Isc and Rn determine Load Current
Simulate the program and read Load current (IL )
from Case 3 tab. Compare the load currents (IL )
obtained from Case 1 tab.
Then click the button to fill the data to the
observation table.
