1.1 INTRODUCTION
In this chapter, we shall review the basic concepts related to electrical networks. The students
must have studied these concepts in their earlier classes. However, a brief review will help them
to understand the contents of chapters that would follow. We will review the basic concepts of
voltage, current, resistance, Ohm’s law, electrical power and electrical energy, series and paral-
lel connections of resistors and division of currents and voltages, and circuit parameters such as
resistor, inductor and capacitor.
After carefully studying this chapter, you should be able to do the following:
