I.PRELIMINARY EXERCISE
(10
marks)
Important Note: You are required to do this exercise
BEFORE the lab session
i. Describe briefly the Superposition and Thevenin theorems by using an
example from
your
own circuit.
ii. For the circuit
in Figure 1, by using Superposition theorem, calculate Il and
Pr at Rr: 10 C), 20 {r,30 C),40 O, 50 Q and 60 O.
iii. Repeat step ii by using Thevenin theorem.
iv. Perform the circuit analysis using PSPICE to validate
your
results.
v. Discuss briefly the irnportance of Thevenin
and
Superposition
heorems itn
circuit analysis.

'Thevenin
and Superposition
Theorems'
IMPORTANT: You need to complete the
PRELIMENARY EXCERCISE before the
laboratory session.
1. Aim:
To solve circuit analysis
problem by using Superposition theorem and
Thevenin theorem.
2. Equipments
provided :
DC
power
supply,
ammeter, multimeter, decade resistance
Instructions
:
Precaution:
i. Set the supply
voltage value to the conect experimental
value before connect
it to the
circuit.
ii. Make
sure the multimeter or ammeters are connected
at a right terminal.
iii. Do not switch
on the supply until the instructor
checks all connections.
Based on the circuit in Figure 1, setup an experiment
to measure the current and
voltage of the
load for R;: 10 A,20 Q, 30 O,
40 C),
50
Q and 60 Q;
i.
based on the original circuit.
ii. by using
superposition theorem.
iii. by using
Thevenin thborem.
Calculate the
power absorbed by Rl from the measurements
in step 2 a.
Compare and
comment on the results of both
theorems against the original circuit
in
terms of voltage,
current and power.
Discuss the
advantages and disadvantages of each
theorem.
