In material science, there is the various classification of all matter in consideration of various important features. Some of the key modes of classification are in relation to electrical conductivity, heat conductivity, magnetism, level of permeability to water or fluids, compressional and tensional strength, ductility, and malleability among others. Today we shall look at one …
Thanks to technology and innovative minds there are multiple varieties of items to choose from in almost every device. Today you cannot go to a selling point and ask car, the next question will always be which type of car. In late 19th and early 20th century, there was one type of a bulb, the …
Introduction Electrical lighting was a phenomenal and outstanding invention in the late 19th century that has been a blessing to the world to date. There were various attempts of what could give the best light for a prolonged period by various scientists. Tungsten was the best settled for all the tested materials. The colour produced …
A rheostat is an electrical component with variable resistance. Basically, it is a variable or adjustable resistor. As the name suggests a resistor resists or inhibits the flow of electric current through a circuit. The amount of current through a circuit is determined by the voltage applied and the total resistance, current is proportional to …

The legacy filament bulb is commonly known as the tungsten bulb. The element has for over a century proven to be a good choice made by our forefathers. There is none like tungsten in performance. To date, the majority of electrical lighting uses a tungsten bulb. Though the technology is first changing, I don’t foresee …
Everyone knows if you need light and you have electricity you only need a bulb and an electrician to install it. You were born post electricity discovery and it may not mean a lot to you what it does. If you have a bulb you know it’s a matter of pressing a switch for you …

One of the key areas in engineering is instrumentation. Engineers want to monitor and control the parameters of machines so that they can work efficiently. A meter is a device used to measure the quantity of a given parameter. Technicians in their work need to know not only the presence given by indicators but as …
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 …
