Sample Problem
Topic: Thévenin and Norton equivalents
Statement of Problem:
Given the circuit shown in the figure below
Determine i
o
and v
o
in the circuit shown above when R
o
is 0, 2, 4, 10, 15, 20, 30, 50, 60, and 70
Ω
.
(Note, this solution will illustrate the process, and display a table of solutions).
Solution
To drastically simplify this process, it would be beneficial to find the Thévenin equivalent circuit for the above circuit from the perspective of R
o
.
To do this, we will make a few source transformations to manipulate the circuit into the Thevenin form.
Source Transformations:
Y Ω
X (V)
Y Ω
X/Y (A)
