Definition of Phase in Electricity In electrical phase it is the expression of relative displacement between waves that have the same frequency. There are two different ways of looking at phases. First, it is when the voltages are out of phase with each other, as with three-phase power, and second, when the voltage is out of … Leer más
Definition of Static Electricity Static electricity can be a nuisance or even a danger. Hair-raising energy can also damage electronic devices and cause explosions. However, properly controlled and handled, it can also be a great blessing to modern life. «Electric charge is a fundamental property of matter». Almost all electric charge in the universe is carried … Leer más
The Beginnings of Electricity: Its Origin From the writings of Thales of Miletus, it seems that the Westerners in their day knew since 600 B.C. that amber is charged by rubbing. But apart from that, there was little real progress until the English scientist William Gilbert in 1600 described the electrification of many substances and coined … Leer más
How is Electricity Produced ? First, to generate electricity, you will need a fuel source, such as coal, gas, hydro or wind power. Regardless of the fuel chosen, most generators work on the same proven principle: turn a turbine to spin magnets surrounded by copper wire, to obtain the flow of electrons through the atoms, which … Leer más
How Did the Discovery of Electricity Happen ? Since electricity is a natural force that exists in our world, it did not have to be invented. However, it had to be discovered and understood. Most people credit Benjamin Franklin with discovering electricity. Benjamin Franklin had one of the greatest scientific minds of his time. He was … Leer más
Definition of Electricity A definition of electricity can be explained in this way, atoms are small particles and, in short, they are the basic components of everything around us, whether our chairs, desks or even our own body. Atoms are made up of even smaller elements, called protons, electrons and neutrons. When electric and magnetic … Leer más
What Electricity Studies: OBJECTIVES The study of electricity makes or helps us understand other physical or natural phenomena and relate them to other scientific branches. We need an electrical current to flow for an electrical system to do anything. Since we cannot see the current, it is not obvious what is happening. We begin with … Leer más
What are the Effects of Electric Current ? The nature of electricity is amazing. Electricity is among the top 10 needs of everyone, as people are more into electric lifestyles these days. There are 3 main effects of electricity as they are: Heating effect Magnetic effect (magnetism) Chemical effect Electric Current Heating Effect As the name … Leer más
Functions of Electricity: What is it For ? Before the invention of electricity, people had to produce energy where and when they needed it. Therefore, they had to make fires out of wood or coal to heat their homes or cook food. The invention of electricity changed all that. It meant that energy could be made … Leer más
