Revision of Circuits and Electronics Part 1 - Superposition, Thévenin and Norton (lecture 3)

What are the properties of  a linear circuit? It has homogeneity and superposition properties.

Homogeneity means a proportional input and output.

Superposition involves -

(1) Finding responses of the circuit to each source acting alone.

(2) Summing the individual responses.

This applies to independent sources.


Thevenin's Theorem -

VTH  -  Open circuit voltage seen at the terminal
RTH -     Resistance of network seen from the port.


Norton's theorem  -
 IN  -  -Short circuit current seen at the port
RN -     same as Thevenin's resistance
