Engineering is a branch of knowledge that the world cannot do without. More than 80% of countries’ budget allocation is drained to the hands of engineers. In fact, you can say that a country’s development equals to engineering projects invested in. The second most junk of budget goes to human resource and still in these …
Hi there! I usually begin with greetings, it’s an African thing, for the rest, I don’t know though I have met some non-Africans who as well really like greetings. This is a follow-up post to the one we shared last week and as promised here comes your read. It’s paramount for me to state that …
An atom contains electron and protons and as a result, there is an electric charge on it due to the balance or unbalance of these particles. Electron contains negative charges and protons contain a positive charge. Like charges repel each other and unlike charges attract each other. These particles create an electric field around then …
If you ever wonder how electricity works, then you are not alone in this. The relation between electricity and the computer is since its invention, and many have a mystical confusion in mind about it. In order to keep your computer system works, you must grasp the basic idea of how a computer works and …
Introduction to Electrical Engineering Electrical engineering is one of the many disciplines within the engineering world. The engineer is to come up with a system that offers a solution to world problems. To achieve this engineering integrates scientific principles with mathematics to design and implement world solutions. Just like other disciplines, these solutions have been …
History and Discovery of Electricity Electricity is one of our most useful sources of energy today. It is hard to imagine how a modem industrial society could exist without electricity. But until the mid-1800s, no one knew much about electricity or how to use it. Until then, electricity was nothing more than a scientific curiosity. …
Measuring Current measuring current on certain troubleshooting jobsis required. You will need to know how much value of current is flowing in part of a circuit. Measuring the current establishes part of the basis for analyzing the circuit which can lead you to the cause of the problem. To measure the current, you use an …

Electric Current Many materials have free electrons. These electrons are not bound tightly to the atoms. They are free to move from one atom to another. When large numbers of these electrons move in one direction, the result is called an electric current. Electric Current in Metals In a metals-for example, copper-the free electrons can …
Electrical Terms Understanding of electrical terms is compulsory for engineers. As you study electricity in your engineering program, and as you work with electricity in the power plants, industrial plants, you will hear, read, and use various electrical terms. These terms have very exact meanings. You must know what each one means if you are …
Definition of Static Electricity Static electricity is electricity that does not move. The word “static” comes from the Greek word “statikos”, meaning the act of making something stand still. Static electricity consists of electrical charges that remain unmoving on an object. Static electricity is usually generated by the physical contact and separation of different kinds …
