The invention of electricity has benefited mankind in several aspects of life ever since the 1800s. Over the course of the past two centuries, scientists have been developing theories that serve as the backbone for various devices today. Such intellectuals have been attempting to understand the credibility and applicability of the already existent theories, such as electricity and magnetism. In addition, they have introduced new concepts by either creating them from scratch, or combining other theories. Electricity, for instance, is a form of energy fueled by the movement of charged particles, called electrons. It is an electrical current if these electrons flow from high to low voltage. If the charged…
One of Nikola Tesla’s greatest discoveries was the electric current. Electric currents are used in every technological advance used today like light bulbs, television, etc. during that point of time, it was very impactful. Nothing like it had been discovered yet. “Tesla…
Electricity is the greatest gift of science to mankind. We have reached a point of our civilization when electricity is used for all purposes. Without it, our existence will be impossible. Electricity is a source of energy. It is produced by a battery or a coil of wires or by dynamo machine. It is produced in thermal station and also in hydro-project.…
You might think that batteries are a modern invention, but batteries were one of the first ways of making electricity. Alessandro Volta discovered the first electric battery in 1800. He made a giant stack of alternating layers of zinc, blotting paper soaked in salt water, and silver. This early design for a battery became known as the voltaic pile.…
Fast-forward to 1729 when, according to Encyclopedia Britannica, another scientifically-minded Englishman, Stephen Gray, discovered that electricity could flow. Before he decided to moisten corks in glass…
* Electromagnetism was discovered in the 19th century, which ultimately leads to the ability to generate electricity, and also to be able to distribute it over wide areas. Thomas Edison in New York in opened the first public electricity utility 1882-marking the first time that electricity was available for domestic and industrial use.…
Electricity is conducted through a conductor, in this case wire, by means of free electrons. The number of free electrons depends on the material and more free electrons means a better conductor, i.e. it has less resistance. For example, gold has more free electrons than iron and, as a result, it is a better conductor. The free electrons are given energy and as a result move and collide with neighbouring free electrons. This happens across the length of the wire and thus electricity is conducted. Resistance is the…
Edison had a rival in the race to develop electricity. His name was George Westinghouse, and he was very interested in alternating current. Edison bought Tesla's ideas, and developed an AC system that lit up the 1893 Chicago World's Fair. Three years later an AC system began turning the energy of Niagara Falls into electricity. Before that Edison relied only on direct current which only went up to one mile while alternating current went over one hundred miles.…
The history of electricity can be traced back to the eighteenth century. The first instance of sensing the phenomenon of electricity was the accidental observation of what was later found out to be neon glow by Framas Bauksbw in 1709 at the Royal Society in London. Luigi Galvani observed moving of the legs of a dead frog when touched with a metal scalpel. This also was later found to have happened due to production of electricity by chemical process. Almost at the same time, Alessandro Volta made the first form of battery. Thus a new phenomenon, the Electric current, was produced which paved the way for the historic and swift growth of Electricity Science. Andre Marie Ampere (1775 to1836) and George Simon Ohm (1787 to 1854) made notable forward leaps in this new sector of science. Later, the invention of electric bulbs, electric motors, etc, initiated the astonishing growth of Electrical Engineering.1…

= 500 ohms In a practical you can use an ammeter and a voltmeter to check the values you calculated for a circuit using ohms law Describe how electricity is transmitted to the home or…
“Energy Story” starts by introducing us to the basis of everything, atoms, and their structure,. The article then walks us through the many components of electricity, and the use of it. “Electrons spin around the center, or nucleus, of atoms, in the same way the moon spins around the earth” The author of this article uses comparisons and similes to help us better grasp some of the concepts, making the article feel like it’s being aimed towards a younger audience. The purpose is help the reader, likely a child or young adult, understand electricity and its many uses.…
In 1820, the Danish scientist Hans Oersted discovered that a conductor carrying an electric current is surrounded by a magnetic field. When he brought a magnetized needle near a wire in which an electric current was flowing, the needle moved. Because a magnetized needle is moved by magnetic forces, the experiment proved that an electric current produces magnetism.…
Electricity is a general term that refers to a variety of phenomena resulting from…
Electricity is a form of energy that form as lightning. Its relationship with electronics is that electronics is that electricity power electronics. In short, without electricity, electronics won’t work. Then what is Electronics? Electronics is any kind of machine that being powered by electricity that helps people to do their jobs faster and faster.…
