electricity?

Question

how is it measured?
in amps, watts, volts, coulombs, watt-hours, moles, faradays, joules? i just don't get it. how are all of these different? why would you use one over the other?

Answer 1

Electricity or current (I) is measured in Amperes.
Watts r units for power I^2R
Volts is a unit for potential difference.
Watt-hrs r used to measure the energy
farads r used to measure capacitance
coulombs r used to measure the charge
Joules r usedf to measure the work=force x distance

Answer 2

For electricity to be used safely, it must be measured and controlled in many ways. Did you know that if you come in contact with just 1 volt of electricity that has a lot of current can be potentially fatal when 1,000 volts with absolutely no current at all won't harm you?

Some measurements of electricity monitor current, such as amps, while voltage monitors the amount of power said current is carrying.

Answer 3

Electricity is nothing but a collection of study of electrons.
Amps is nothing but speed of charge or charge passing through a unit cross sectional area in 1 sec.
Watts is unit of power that joules per unit time
Volts is the potential difference with respect to charge
Coulombs is unit of charge
Watt-Hours is unit of energy like watts multiplied by time.
U can have analogy like this
A tank kept at a certain height having the amount of water. The potential energy of water by virtue of its height is analogous to the Voltage. if we open the tap of the tank the force with which it falls(water) is analogous to the current or amps and the time till which it can deliver that force (roughly) is equal to the energy.

Answer 4

The Electricity is first of all Electron.

What is the electron?
=================
Robert Milliken, who measured a charge of electron, in his
Nobel speech ( 1923) told, that he knew nothing about “last essence of electron”.
In that case there is one old joke.
One professor asked a student:
“ What is an electron?”
“ Ah, God damn it! I have forgotten. And in fact even in the morning I knew it. ”-
the student answered.
“ You should recollect it without fail, - professor said – because you were
the unique person who knew, what electron was, and you had suddenly forgotten!”
This old joke does not grow old.
And today a question: “What is the electron?” remains without answer.
How the electron looks nobody knows.

There isn,t the Maxwell's theory / SRT without electron.
The electron is a main and single hero in the Maxwell's theory and SRT.
1) What does the electron do in Maxwell's theory?
Maxwell's equations have no relation to the movement of the electron.
They describe the distribution of electromagnetic waves
but not the movement of a particle such as an electron.
In Maxwell's theory, the electron is considered local,
as though the particle is "at rest".
This means that it particle does not move rectilinearly,
but rotates around the diameter
(has the form of a sphere- geoid).
The electron rotates around of its diameter with the speed
more than c=1. / Tachion theory/.
Therefore:
1.The electron has an electrical charge e =±√ hca
2. This electron /charge has energy E = hw
The rotation of the electron creates electrical waves.
* * *
But everybody knows, that an electron is not a firm sphere.
Everybody knows, that its form can be changed.
And these changes describes by SRT.
2) What does the electron do in SRT ?
At the beginning of the last century many scientists
(Einstein, Lorents, Fitzgerald, Poincare, Abraham)
were interested in the question:
“What will take place, if the electron (Maxwell's), creating
an electrical field, begins to move - rectilinearly? “
All of them came to the conclusion that there would be
radical changes with the electron.
These changes are described by the Lorentz transformations.
That is, when the originally rotating electron (sphere) begins
to move rectilinearly, during movement it gradually
will change its geometrical form.
* * *
But nobody understands the borders of the electron,s changes.
So, what are the borders of this change?
Quantum theory gives an answer to this question.
It says that at the interaction of the electron with the vacuum,
its energy and mass become infinite.
Physicists do not understand what to do with infinite sizes,
and therefore they have invented "a method of renormalization",
a method "to sweep the dust under the carpet" / Feynman./
This method is abstract.
The situation can be understood in another way.
Electrons, having the geometrical form of a sphere, lost their volume
and turned into an indefinitely flat circle.
In this reason, infinite sizes of the electron occurred.
But in physics we know only one particle which has the form of a flat circle.
It is a quantum of light, which flies rectilinearly with speed c= 1.
Therefore, the electron can turns only into a quantum of light.
That is why, the electron and /or a quantum of light
is the same particle in different states.
* * *
It is proved, when electron leaves atom, its electric field changes.
The spherical field will be transformed to an ellipse field.
And in process of his removal the ellipse field is more and more extended.
And in a limit (at the moment of breaking-off )
the electron gets the form of a string.
/String theory/.
Therefore, electron can have the different geometrical forms:
circle, sphere and string.
* * *
In the books it is written, that electrons interact among
themselves with the help of a quantum of light.
In the books it is written that an electron in an atom passing
from one orbit to another radiates a quantum of light.
It should be understood as follows.
The electron has a quantum of light in a “pocket” or under a "shirt"
which it gives freedom from time to time.
Why is it necessary for the electron to hide a quantum of light?
================================
Many years ago man has accustomed some wild
animals (wolf, horse, cat, bull , etc.)
and has made them domestic ones.
But the man understands badly the four-footed friends.
In 1897 J. J. Thomson opened new particle - electron.
Gradually man has accustomed electron to work for him.
But the man does not understand what an electron is.
