what is electricty?

Answer 1

What is electricity? This question is impossible to answer because the word "Electricity" has several contradictory meanings. These different meanings are incompatible, and the contradictions confuse everyone. If you don't understand electricity, you're not alone. Even teachers, engineers, and scientists have a hard time grasping the concept.

Answer 2

Electricity is a naturally occurring force that has existed all around us. Humans have noticed this force for many centuries. Ancient man believed that electricity was some form of magic because they did not understand it. Greek philosophers noticed that when a piece of amber was rubbed with cloth, it would attract pieces of straw. They recorded the first references to electrical effects such as static electricity and lightning over 2,500 years ago.

It was not until 1600 that a man named Dr. William Gilbert coined the term “electrica,” a Latin word which describes the static that occurs when amber and other materials are rubbed. This is probably where the word “electricity” came from. Electricity and magnetism are natural forces that are very closely related to one another.

Electricity is a term used to describe the energy produced (usually to perform work) when electrons are caused to directional (not randomly) flow from atom to atom. In fact, the day-to-day products that we all benefit from, rely on the movement of electrons. This movement of electrons between atoms is called electrical current.

It is very important to have a way to measure and quantify the flow of electrical current. When current flow is controlled it can be used to do useful work. Electricity can be very dangerous and it is important to know something about it in order to work with it safely. The flow of electrons is measured in units called amperes. The term amps is often used for short. An amp is the amount of electrical current that exists when a number of electrons, having one coulomb (ku`-lum) of charge, move past a given point in one second. A coulomb is the charge carried by 6.25 x 10^18 electrons. 6.25 x 10^18 is scientific notation for 6,250,000,000,000,000,000. That is a lot of electrons moving past a given point in one second!

Answer 3

Electricity is the flow of electrons from a negative to a positive potential.it is mearured in kilo-volt-amps (kVA). the driving force of electricity is called the volt, hence the phrase potential difference. the ability to use this work is called the amp (current). The equation V=RI is known as ohms law and is the fundemental law by which electricity is evaluated. Voltage is directly proportional Current, so the higher the voltage the lower the current and vice-versa.

Answer 4

Flow of electrons in a closed path is called electric current, which inturn helps in various conversion for domestic and industrial applications is called Electricity.

Electrical energy -- > mechanical (motor), Sound (speaker),Light (tube light & lamp) Heat(Heater) and so on

Answer 5

Electricity (from Greek ήλεκτρον (electron) "amber") is a general term for the variety of phenomena resulting from the presence and flow of electric charge. Together with magnetism, it constitutes the fundamental interaction known as electromagnetism. It includes many well-known physical phenomena such as lightning, electric fields and electric currents, and is put to use in industrial applications such as electronics and electric power.

Answer 6

Misspelled, to begin with.

Electricity, as we use it is the combination of the electromotive force being used to push/pull electrons through a conductor. This electromotive force can be used to transfer/transmit energy and power.

The power used to move the electrons (forming the electricity), at the power plant, is used to run things in your home, work, etc.

The term electricity is a bit vague, but I was attempting to answer your question in terms of what I thought your were asking.

Answer 7

The movement of charge (like electrons or ions.) Static electricity is simply the separation of charge, the positive is in a different place to the negative.

Answer 8

Electricity is the flow of electrons through a conductor from the source and back again.

Answer 9

e·lec·tric·i·ty (ĭ-lěk-trĭs'ĭ-tē, ē'lěk-) Pronunciation Key
n.

The physical phenomena arising from the behavior of electrons and protons that is caused by the attraction of particles with opposite charges and the repulsion of particles with the same charge.

Answer 10

Electricity is a myth created by Con Edison in order to make consumers pay large monthly bills.
