SUPERPOSITION THEOREM

Page 4: Circuit Theorem

4BEE1113 Chapter 4 : Circuit TheoremNH-credit to NHA

Superposition Theorem

Superposition : the voltage across (or current through) an element in a linear circuits is the algebraic sum of the voltage across (or current through) that element due to each independent source acting alone.

Current Source open circuit(0 A)

Voltage Source short circuit (0 V)

Page 5: Circuit Theorem

Step to apply:

1. Turn off all independent sources except one source. Find the output (voltage or current) due to that active source.

2. Repeat step 1 for each other independent sources.

3. Find the total contribution by adding algebraically all the contribution due to the independent source.

SOURCE TRANSFORMATION

Source Transformation

Source transformation :

replacing a voltage source vs in

series with a impedance Z by a

current source is in parallel with a

impedance Z, or vice versa.

THEVENIN’S THEOREM

Page 14: Circuit Theorem

14BEE1113 Chapter 4 : Circuit TheoremNH-credit to NHA

Thevenin’s Theorem

Thevenin’s theorem : a linear two terminal circuit can be replaced by an equivalent circuit consisting of a voltage VTh in series with an impedance ZTh ,

where VTh is the open circuit voltage at

the terminals and ZTh is the input or

equivalent impedance at the terminals when the independent source are turned off.

NORTON’S THEOREM

Page 22: Circuit Theorem

22BEE1113 Chapter 4 : Circuit TheoremNH-credit to NHA

Norton’s Theorem : a linear two-terminal circuit can be replaced by an equivalent

circuit consisting of a current source IN in

parallel with an impendence ZN, where IN is

the short circuit current through the

terminals and ZN is the input or equivalent

impedance at the terminals when the independent source are turned off.
