1.1 Introduction
Today we live in a predominantly electrical world. Electrical technology is a driving force
in the changes that are occurring in every engineering discipline. For example, surveying
is now done using lasers and electronic range finders.
Circuit analysis is the foundation for electrical technology. An indepth knowledge of
circuit analysis provides an understanding of such things as cause and effect, feedback
and control and, stability and oscillations. Moreover, the critical importance is the fact
that the concepts of electrical circuit can also be applied to economic and social systems.
Thus, the applications and ramifications of circuit analysis are immense.
In this chapter, we shall introduce some of the basic quantities that will be used
throughout the text. An electric circuit or electric network is an interconnection
of electrical elements linked together in a closed path so that an electric current
may continuously flow. Alternatively, an electric circuit is essentially a pipe-line that
facilitates the transfer of charge from one point to another.
1.2 Current, voltage, power and energy
The most elementary quantity in the analysis of electric circuits is the electric charge.
Our interest in electric charge is centered around its motion results in an energy transfer.
Charge is the intrinsic property of matter responsible for electrical phenomena. The
quantity of charge q can be expressed in terms of the charge on one electron. which is
1:602 10 19 coulombs. Thus, 1 coulomb is the charge on 6:24 1018 electrons. The
current flows through a specified area A and is defined by the electric charge passing
through that area per unit time. Thus we define q as the charge expressed in coulombs.
Charge is the quantity of electricity responsible for electric phenomena.
