From its beginnings in the late nineteenth century, electrical engineering has blossomed from focusing on electrical circuits for power, telegraphy and telephony to focusing on a much broader range of disciplines. However, the underlying themes are relevant today: Powercreation and transmission and information
Determine the power for the source and for each branch element in the following circuit. Show that power is conserved. How much energy is delivered by a 20 hp motor in 15 minutes? If the motor is 92% efficient, how much energy is consumed by the motor during that time? (1 …

Then we will step through each of these topics in detail: Section Title Page Number • Introduction to Electricity 3 • Characteristics 3 • Current 4 • Voltage 5 • Resistance 6 • Review 1 9 ...
The effects of electric current flow can be detected by the presence of one or more of the following effects: light, heat, magnetism, chemical, pressure and friction For example, heat is produced when an electric current is passed through a resistive heating element. Light is produced when an electric current flows through
Electric charge is a basic property of electrons, protons and other subatomic particles. Opposite charges attract each other and same charges repel each other. This makes electrons and protons stick together to form atoms. One foundational unit of electrical measurement is coulomb, which is a measure of electric charge proportional to the number
Basic Electrical Engg. 2 FUNDAMENTALS CHAPTER-1 Concept of current flow The smallest known quantity of electric charge is the charge of an electron. So, all quantities of charge are expressed in multiples of this basic or fundamental unit i.e. charge of an electron.

The primary purpose of an electric circuit is to move or transfer charges along spec-i ed paths. This motion of charge constitutes an ‘electric current’, denoted by ior I. Formally, the current is the time rate of change of charge. The unit of current is ‘ampere (A)’.
