What is Electricity ?

Electricity is an invisible force. The force is the attraction or opposition between charges. I am not going to get into the electron and proton in the atom but you should have some understanding of how electrons flow through a conductor.

Or Electricity is the set of physical phenomena associated with the presence of electric charge. Although initially considered a phenomenon separate from magnetism, since the development of Maxwell’s equations, both are recognized as part of a single phenomenon: electromagnetism.

Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. In addition, electricity is at the heart of many modern technologies.

The main principal behind current flow or the flow of electrons through a wire is the potential difference between charges. As we are aware Magnets have north and south poles and if we bring the same poles together there is a force that is trying to repel them but on the same note if we use opposite sides of a magnet the will attract.

On a battery we have a positive and a negative terminal (opposites).  If we were to attach a wire to one end of the battery and bring it close to the other end of the battery,  as soon as we were close enough where the potential difference (voltage) was able to overcome the resistance of the air, electrons would flow or attract and we would have a spark. Electrons with a path to travel will be attracted to the opposite terminal and repelled from the alike terminal.

Electricity is energy that can be transported

An electric circuit consists of an energy source, such as a battery or power supply, and interconnected electrical components implementing a useful function. The connections are formed by wires, also known as conductors, which are made of materials such as copper or some other metal that can conduct electricity.

Electrical charge transported across a conductor is called electric current. Charge is carried by electrons, which are negatively charged, or by positively charged ions in the conductor.

Electrical phenomena have been studied since antiquity, though progress in theoretical understanding remained slow until the seventeenth and eighteenth centuries. Even then, practical applications for electricity were few, and it would not be until the late nineteenth century that engineers were able to put it to industrial and residential use.

The rapid expansion in electrical technology at this time transformed industry and society. Electricity’s extraordinary versatility means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation. Electrical power is now the backbone of modern industrial society. [www.blogteknisi.com]
