Telecommunications • Telecommunication is the transmission of messages, over significant distances. • In the modern age, telecommunications has typically involved the use of electric means such as the telegraph, thetelephone, and the teletype, the use of fiber optics and their associated electronics, and/or the use of the internet.. • These systems of communications all required the use of conducting metal wires
Control Systems Engineering • Applies control theory to design systems with predictable behaviors. • The practice uses sensors to obtain measurements used to give feedback to the input actuators that can make corrections toward desired performance • When a device is designed to perform without the need of human inputs for correction it is called automatic control.
Electronics Engineering • Uses the scientific knowledge of the behavior and effects of electrons to develop components, devices, systems, or equipment
Power Engineering • Deals with the generation, transmission and distribution of electric power as well as the electrical devices connected to such systems including generators, motors and transformers. • Concerned with the problems of three-phase AC power and conversion between AC and DC power as well as the development of specialized power systems such as those used in aircraft or for electric railway networks.
Basic Quantities • Voltage is a representation of the electric potential energy per unit charge.. In other words, it is a measurement of the energy contained within an electric field, or an electric circuit, at a given point • Electrical current is a measure of the amount of electrical charge transferred per unit time. It represents the flow of electrons through a conductive material. • Electrical resistance of an object is a measure of its opposition to the passage of a steady electric current. An object of uniform cross section will have a resistance proportional to its length and inversely proportional to its cross-sectional area, and proportional to the resistivity of the material.
