Electricity is the life blood of the modern society making electrical engineers crucial to our every day life. You can see the work of an electrical engineer in many commercial buildings, projects and factories. They are employed wiring buildings, building and repairing machines and making sure every area of our life gets the power it needs from electricity. Learn about the theories, and models of electricity that make this possible, as well as pratical application.
Electric shock from a high-voltage source can be fatal. While the victim might still be in after-shock trauma, his life depends on people around him. Many of us might not know how to react under such circumstances. Here are some first aid tips and a brief guide on what you can do for the victim.
Writing a CV requires a lot of forethought. It has to be well presented and well organized. It is a tool, which is beneficial for both the company hiring as well as the applicant. The hiring company uses a CV to find answers to the questions as to why should you be hired.
The credit for inventing alternating electric current (AC), which is used in everyday life, goes to Nikola Tesla, an inventor beyond compare. He not only gave AC current to mankind, but was also responsible for setting up the first hydroelectric plant. Read about his life and inventions.
Slip Ring induction motor’s speed can be controlled by injecting e.m.f into its rotor circuit. Read here to know about the Kramer system of injecting e.m.f and Scherbius system for controlling the speed of slip ring motors. Also understand how the cascaded system works.
To make single phase motor a self starting one, it can be converted into a two –phase motor during the starting period. For this purpose, along with main winding in the stator an auxiliary winding is provided. The two windings should be 90 degrees electrically apart.
We studied about the Superposition theorem and Kirchhoff’s laws in previous articles. Another important network theorem is the Thevenin’s theorem which is being described in this article, and is used to convert linear circuits containing multiple resistances and sources of emf into a simple circuit
We live in a world of networks and you surely must be using one right now (since you are reading this article on the Internet – one of the largest networks), but networks are not only about computers alone. Electric circuits also have networks and network theorems which govern their behaviour.
