Introduction

Electrical and Electronic Engineering is a professional Engineering discipline that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late ninetieth century with the commercialization of the electric telegraph and electrical power supply. The field now covers a range of sub-disciplines including those that deal with power, optoelectronics, digital electronics, analog electronics, computer science, artificial intelligence, control systems, electronics, signal processing and telecommunications. Power Engineering deals with the generation, transmission and distribution of electricity as well as the design of a range of related devices. These include transformers, electric generators, electric motors and power electronics. The generation of electric power using alternative/ renewable energy sources has become very popular nowadays. Though the extensive use of power electronic devices has adversely affected power quality, researchers have found remedial solutions to tackle power quality issues. Control engineering focuses on the modeling of a diverse range of dynamic systems and the design of controllers that will cause these systems to behave in the desired manner. To implement such controllers electrical engineers may use electrical circuits, digital signal processors and microcontrollers.

The term Electrical Engineering may or may not encompass electronic engineering. Where a distinction is made, Electrical Engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas Electronic Engineering deals with the study of small-scale electronic systems including computers and integrated circuits. Another way of looking at the distinction is that electrical Engineers are usually concerned with using electricity to transmit energy, while electronics Engineers are concerned with using electricity to transmit information.
