Topic: Quantity of electricity

	Electricity - LoveToKnow 1911
		The two great branches of electrical theory which concern the phenomena of electricity at rest, or " frictional " or " static " electricity, and of electricity in motion, or electric currents, are treated in two separate articles, Electrostatics and Electrokinetics.
		John Canton (1718-1772) made the important contribution to knowledge that electricity of either sign could be produced on nearly any body by friction with appropriate substances, and that a rod of glass roughened on one half was excited negatively in the rough part and positively in the smooth part by friction with the same rubber.
		Electric attractions and repulsions were, however, regarded as differential actions in which the mutual repulsion of the particles of electricity operated, so to speak, in antagonism to the mutual attraction of particles of matter for one another and of particles of electricity for matter.

		In this sense, the phrase "quantity of electricity" is used interchangeably with the phrases "charge of electricity" and "quantity of charge." There are two types of electricity or charge: we call one kind of charge positive and the other negative.
		The potential of earth ground is defined as zero by convention, and the electrical conductivity between similarly buried electrodes is considered to be low enough that all earth terminals are effectively at the same voltage.
		Rather than using the word electricity to refer to the quantity of electric charge, many sources instead say that electricity is the quantity of electromagnetic energy measured in joules or kilowatt-hours.

	Quantity of electricity - Wikipedia, the free encyclopedia
		Quantity of electricity is now regarded as an archaic usage, and it has slowly been replaced by the terms charge of electricity, then quantity of electric charge, and today simply charge.
		If historical physicists discuss quantities of "electricity" implying "electric charge," yet the modern reader assumes they're speaking of electrical energy, the writings of those physicists will be quite difficult to understand.
		For example, in the modern SI units of physics, the coulomb is defined both as the unit of electric charge and also the unit quantity of electricity.

	Basic Electricity
		-- A unit of electrical charge; the quantity of electricity passing in one second through a circuit in which the rate of flow is one ampere.
		Electricity, no matter how produced is believed to be one and the same thing.
		-- The law first stated by Joule, that the quantity of heat developed in a conductor by the passage of an electric current is proportional to the resistance of the conductor, to the square of the strength of the current, and to the duration of the flow.

		Instead, they agree that an electric current is a flow of "electricity." They also agree that electrons and protons carry charges of "electricity," and that quantities of electricity are to be measured in units of charge rather than units of energy.
		Coulomb (unit quantity of electricity) -- the quantity of electricity transported in 1 sec by a current of 1 A. A unit quantity of electricity.

		Many sources say that "electricity" is the quantity electricity usage for appliances of electrical energy measured in joules or kilowatt-hours.
		The symbol Q is used in equations to represent the quantity of electricity or charge.
		The potential of earth (ground) is defined as zero by convention, nature flow of electricity and the electrical resistance between similarly buried electrodes is usually low enough that all earth terminals within a given area can be considered to be at the same voltage.

		The separation of a salt into two parts by the electric current, he called electrolysis; the surfaces from which the current passes into, and out of, an electrolysable compound, he named electrodes; the substances liberated at the electrodes, he called ions.
		Taking as his unit the quantity of electricity which liberates one gram of hydrogen from an electrolysable compound of that element, he showed that the weights of different ions liberated from compounds by unit quantity of electricity are in the proportion of their chemical equivalents.
		In 1834, Faraday said—“The forces called electricity and chemical affinity are one and the same.” Faraday distinguished the intensity of electricity from the quantity of it, and indicated the meaning of each of these factors.

	What is Electricity: definitions (Site not responding. Last check: 2007-11-04)
		Electricity has mass, although for electrons the mass per cubic volume is very small (the electrons of a wire are thousands of times lighter than the copper atoms, yet the number of electrons rivals the number of atoms.
		Instead electricity is composed of electrostatic fields and magnetic fields which exist in the region surrounding the wires.
		If "electricity" is the current, then "electricity" appears whenever the electrons of a metal wire are forced to flow (that is, electrons moving relative to the protons of the copper atoms in that wire.) And when the flow is halted, the "electricity" vanishes, even though the electrons are still there inside the wires.

	Why Electricity is Impossible to Understand (Site not responding. Last check: 2007-11-04)
		Lightning is "electricity" because it is an electrical phenomenon.
		Electricity is thought to be abstract, complicated, confusing, mysterious, and invisible, with behavior which frequently goes against common sense, and anyone who can't understand it has just not worked hard enough.
		Example: electricity travels at nearly the speed of light (yes, this is true if "electricity" is defined as meaning "EM energy.") Example: electricity is composed of particles called electrons (yes, if "electricity" is defined as meaning "charge") But the student will never grasp electrical physics now, because these two concepts turn to garbage when combined.

		Electricity (from Greek ήλεκτρον (electron) "amber") is a general term for the variety of phenomena resulting from the presence and flow of electric charge.
		Though Benjamin Franklin's famous "invention" of electricity by flying a kite in a thunderstorm turned out to be more fiction than fact, his theories on the relationship between lightning and static electricity sparked the interest of later scientists whose work provided the basis for modern electrical technology.
		Examples of electric currents include metallic conduction, where electrons flow through a conductor or conductors such as a metal wire, and electrolysis, where ions (charged atoms) flow through liquids.
