The document presents a presentation on the superposition theorem in circuit analysis, explaining how it allows for the simplification of complex circuits by considering each independent source separately. It outlines steps for applying the theorem, including identifying, deactivating, and calculating the response of sources, and includes examples of both resistive and reactive circuits. The document concludes by emphasizing the power and limitations of the superposition theorem in circuit analysis.

Superposition Theorem

2. Introduction to Superposition Theorem
The Superposition Theorem states that in a linear circuit with multiple
independent sources, the total response of the circuit is the sum of the responses
due to each independent source acting alone.
The theorem allows us to analyze complex circuits by breaking them down into
simpler circuits. It is applicable to circuits containing multiple independent
sources, including voltage sources and current sources.

3. Linearity of Circuits
Proportionality
If the input is doubled,
the output is also
doubled. This holds true
for all inputs, regardless
of their magnitude.
Homogeneity
The output of a linear
circuit is directly
proportional to the
input. This means that if
the input is multiplied by
a constant, the output is
also multiplied by the
same constant.
Additivity
The output of a linear circuit is the sum of the individual
outputs due to each independent source acting alone.

4. Application of Superposition Theorem
Identify Sources
Identify all independent
sources in the circuit.
Deactivate Sources
Deactivate all
independent sources
except one. Replace
voltage sources with
short circuits and current
sources with open
circuits.
Calculate Response
Calculate the response of
the circuit due to the
active source.
Repeat Steps
Repeat steps 2 and 3 for each
independent source, deactivating all
other sources in each step.
Superimpose Responses
Add the individual responses to get the
total response of the circuit.

5. Example 1: Resistive Circuit
Voltage Source
A voltage source with a known voltage.
Resistors
Passive elements that resist the flow of current.
Current
The flow of charge through the circuit.

6. Example 2: Reactive Circuit
1
The Superposition
Theorem can also be
applied to reactive
circuits.
2
Reactive circuits contain
capacitors and inductors,
which store energy in
electric and magnetic
fields.
3
The response of a
reactive circuit is time-
dependent and can be
represented by
sinusoidal functions.

7. Conclusion and Key
Takeaways
The Superposition Theorem is a powerful tool for
analyzing circuits. It simplifies complex circuits by
breaking them down into simpler components
and summing their individual responses. While it
is a valuable technique, it has limitations and
should be used only when appropriate.
