How to Generate Electricity – How is Electricity Generated

Electricity is the energy made available by the flow of electric charge through a conductor. It is carried by wires or produced by batteries and is used to power machines. Electricity is lifeline of modern world. There are different types of electricity generated through renewable and non-renewable sources of energy.

What is Electricity?

Electricity is flow of electrons from one body to another. In order to understand this is some detail, it is important to understand the structure of an atom. An atom consists of three elements – electrons, protons and neutrons. Electrons are negatively charged (-) particles, protons are positively charged particles (+) and neutrons are neutrally charged or they have no charge. Example: A and B are two objects with 10 electrons and 10 protons each. Due to friction or any other reason, 2 electrons from the outer orbit of object A flows away to object B. Now there are 8 electrons in object A and 12 electrons in object B. The net result of this flow of electrons is that object B will get negatively charged due to excess electrons and object A will get positively charged because of deficit of electrons. This is how electricity is generated.

History of Electricity

In Physics, the law of conservation of energy states that energy can neither be created nor be destroyed. This means that in order to generate electricity, another kind of energy should be used as fuel.

• Thomas Seebeck (1770-1831): Discovered the “Seebeck Effect”.
• Michael Faraday (1791-1867): Electromagnetic induction. He also explained how electric currents works.
• James Maxwell (1831-1879): Translated Faraday’s theories into mathematical expressions.
• Thomas Alva Edison (1847-1931): Invented the electric bulb
• Nikola Tesla: Devised the polyphase alternating-current systems that form the modern electrical power industry.
• Otto Hahn (1879-1968): Explained the process of nuclear fission by which nuclei of atoms of heavy elements can break into smaller nuclei, in the process releasing large quantities of energy.
• Albert Einstein (1879-1955): Explained that one gram of mass can be converted into a torrential amount of energy

Modern day electricity is a result of all the hard work done by above mentioned great people.

Static Electricity

Static electricity is an electrical charge at rest. This is created by an imbalance of electrons that stay on a specific surface, or in the environmental air. The imbalance of electrons is caused by absence or surplus of electrons. This creates an electrical field that is capable of influencing other objects at a distance. Lightening is an example of static electricity.

electronics assemblesd electronic history

Once the printed circuit board (PCB) is complete, electronic components must be assembled to form a functional printed circuitassembly, or PCA or PCBA (printed circuit board assembly). 

In through-hole PCA, component leads are inserted in holes and thus the name Thru-Hole. In surface-mount PCA, components are placed on pads or lands on the outer surfaces of the PCB.
In both kinds of assembly (Thru-Hole and SMT), component leads are electrically and mechanically fixed to the board with solder. In case of Thru-Hole, solder wire or solder bar is used while in SMT, solder balls of solder paste is used.

Basic Electronics Tutorial : Lean the basics of electronics including electronics circuits, PCB (Printed Circuit Board), Electronics Design, Laws of Electronics. This article is designed for the beginner to electronics. The more experienced hobbyist will probably learn some new things as well, since there is a good deal of information here that most non-professionals will be unaware of.

Introduction to Electronics: 1745 in Leyden (Netherlands), discover the Leyden jar. The firstelectrical capacitor - a storage mechanism for an electrical charge. The first ones were a glass jar filled with water -two wires suspended in the water. Muschenbrock got such a shock out of the first jar he experimented with that he nearly died. Later, the water was replaced with metal foils wrapped so there was insulation between the layers of foil- the two wires are attached to the ends of the sheets of  foil. This gave birth to Modern Electronics.
Definition of electronics: Electronics is the branch of science that deals with the study of flow and control of electrons (electricity) and the study of their behavior and effects in vacuums, gases, and semiconductors, and with devices using such electrons. This control of electrons is accomplished by devices that resist, carry, select, steer, switch, store, manipulate, and exploit the electron

Soldering the electronics tech

All about soldering including, hand soldering, thru-hole soldering, SMD soldering,  wave soldering selective soldering, RoHS, Lead-Free (Pb-Free), BGA Soldering and Rework, Desoldering, Solder Wire, Solder Flux, Solder Bar, Soldering Technology, How to Solder and more.

Soldering is accomplished by quickly heating the metal parts to be joined, and then applying a flux and a solder to the mating surfaces. The finished solder joint metallurgically bonds the parts forming an excellent electrical connection between wires and a strong mechanical joint between the metal parts. Heat is applied with a soldering iron or other means. The flux is a chemical cleaner which prepares the hot surfaces for the molten solder. The solder is a low melting point alloy of non ferrous metals.

Electronics History - Origin and Development of History Electronic

 Today in the twenty first century, many consumer, military, and recreational products are made with electronic devices. Perhaps, in the future we will see even more uses of Electronics. Almost all phases of modern technological society use Electronics, even this computer that is being used to type this script. The home, car, or the workplace all use Electronics. We all use Electronics but very few know the complex history behind Electronics. The purpose of this site is to explain the history, origin and development of Electronics.

It is important to know the History of Electronics (technology) so students better understand their electronic gadgets they use everyday on an increasing bases. That is, cell phones, ATMs, calculators, cars, fax machines, computers, copiers, radios, TV, etc.

To understand the interesting history of these electronic devices helps explain why science and technology are important, too. Without these technologies and electronics, our status in the world community would be diminished, therefore it is important to study the history of electronics, science and technology.

The historical approach to Electronics is a real task because of the tremendous amount of material that must be sorted through. Electronics is a vast sea of scientific information.

I will try my best to explain the origin, history and development of electronics here.

Dish receiver technology

In order to take advantage of the hundreds of channels that a satellite dish has to offer, users must have a set-top box or receiver. This connects to the television and allows users to browse through the available programs. Dish Network is one of the top satellite providers in the US and offers several models of receivers for customers. The options range from basic set-top boxes for a single television to whole-home DVRs that allow people to record their favorite shows and watch them on any television in the house. When shopping for a new Dish Network satellite TV receiver, shoppers should look at the top models and what each has to offer to see which one best meets their needs.
