What are the Principles of Electrical Engineering?

Electrical engineering deals with the understanding of designing, working and functioning of different types of equipment. The types of equipment mentioned here are the ones which use electricity, electronics and electromagnetism for their operations. To understand the working of these pieces of equipment, it is essential to understand the basic principles of electrical engineering on which these pieces of equipment are based. The aspiring Electrical engineers have to be very well aware of these principles as these form the basis of all the education, they are going to get about being an electrical engineer. Below are the principles on which electrical engineering is based on

Electricity

Electricity is nothing but a form of energy which is the flow of electrons. These electrons are responsible for creating charge and generate electricity. The electricity is used for numerous purposes in our daily life be it switching on the light for brightness or to charge the phone or laptop or various other chores. Electricity is undoubtedly the most commonly used source of energy.

The basic principles of electrical engineering are based on the three parameters of electricity

The Volt

The electromotive force or the Volt is a quantitative expression of the potential difference in charge between two points in the electrical field. The flow of the electric current depends upon how the Voltage is, higher the flow of Voltage more the electricity. Voltage is measured in Volt, which is named after an Italian physicist Alessandro Volta. Voltage can be understood by a simple definition that it is the amount of potential energy between two points on a circuit. If one point has more charge than others, then the difference between these charges is called Voltage.

The Ampere

The Ampere defines the flow rate of the electric current, in other words, it is a unit of measure of the rate of electric current in an electrical conductor. It is essential to be able to quantify the current flow in the system, and this will help to estimate the performance of the circuit, which has to be defined. A unit is required to gauge the performance of the circuit, and this unit is called Ampere or amp. The unit of electric current is named after the ‘Father of Electrodynamics’ a French Physicist and Mathematician called Andre-Marie Ampere.

The Ohm

The unit of resistance in a conductor is known as the Ohm. The unit of resistance is influenced by three things, they are the size of the conductor, the material of the conductor and the temperature of the conductor. If the length of the conductor increase or the diameter of the conductor decreases the resistance of the conductor to increase and on the contrary, if the material of the conductor is more conductive then the resistance of the conductor decreases. And if there is a rise in temperature, then the resistance of the conductor also increases. This unit of resistance is named after German physicist Georg Simon Ohm.

Ohm’s Law

Ohm’s Law gives the correlation between electric current (I), Voltage (V), and resistance (R) in a conductor.

Ohm’s Law is expressed as V = I × R

Where: V = volts, I = amps, R = Ohms

These are the fundamental principles of electrical engineering which student who want to pursue electrical engineering should be aware. MIT Academy of Engineering (MITAOE), Alandi, Pune is the Engineering institute in Pune which offers the undergraduate and postgraduate courses for electrical engineering. Although the concepts of electrical engineering are overwhelming MIT Academy of Engineering (MITAOE), have a learning-centred approach, the faculty gives personal attention to the students, and the institute thrives on making the teaching and learning process more effective. This makes the students understand the concept clearer and better.
