Linearity Property
It is the property of an element describing a linear relationship
between cause and effect.
A linear circuit is one whose output is linearly related (or
directly proportional) to its input.

Thevenins Theorem (Revision)
It states that a linear two-terminal circuit
consist of sources and resistors (Fig. a) can be
replaced by an equivalent circuit (Fig. b)
consisting of a voltage source VTH in series with
a resistor RTH,
where
VTH is the open-c

Capacitor
Capacitor an Intro
A capacitor (originally known as condenser) is a passive twoterminal electrical device used to store charge in an electric field.
The forms of practical capacitors vary widely, but they all contain at
least two electrical co

Inductor and transients
Inductor
Inductance is the property of a circuit
by which an emf is induced into the
circuit by the change of flux linkages
produced by a change in current.
Inductor is a component that has the
property of inductance. It is a coi

Single phase system
Polyphase system
Circuits or systems in which the ac
sources operate at the same

Circuit Analysis in s-domain
What topics did we study in
circuit analysis?
We studied circuits without capacitors or
inductors and how to represent them by mesh
current equations or node voltage equations.
