Thvenins Theorem
Any circuit with sources (dependent and/or
independent) and resistors can be
replaced by an equivalent circuit
containing a single voltage source and a
single resistor

Example 5.2
Superposition
In any linear circuit containing multiple
independent sources, the current or voltage
at any point in the circuit may be calculated
as the algebraic sum of the individual
contributions

Independent vs. Dependent Sources
An independent source (voltage or current)
may be DC (constant) or time-varying, but
does not depend on other voltages or
