All language subtitles for 4. Definition of an Electric charge--- [ FreeCourseWeb.com ] ---

Now we need to identify what is an electric source.

If someone asks me what is an electrical charge so I will tell him that a charge is an electrical property

of the atomic particles of which a matter consists of and they are measured in columns.

So ze charge is an electrical property of the atomic particles.

An example of the charge.

If you understand what is an atom an atom has and neutrons protons and Z and negative charges which

is the electrons.

Of course as there are other types of material we are not going to see them because it is an electric

course and not physics of course.

But anyway ze have protons having AB positive charges and ze neutrons having annual trolley charge and

dizzy electrons are represented by negative charges.

So all of this the electrons Zi protons and neutrons are called a source something which you having

AB positive or negative and this charges are forming our atoms.

So each atom consisting of electrons protons and neutrons the electron for example is at negative one

and negative charge and its magnitudes equal to as I call them one point six zero two multiplied by

Tempel negative 19 column.

So this is equivalent to two one electron so we need to understand now what is the benefit of electric

charges.

Here we have our four hour battery or our source of electricity.

So what does this battery do.

Is this battery has to terminal this terminal and this terminal at Terminal which is a positive terminal

and another one which is the negative terminal.

So what does or what happens here.

Ze negative here is representing our electrons okay.

And the year is the positive representing our positive charges or we can say ze protons.

Okay but actually we can not say they are protons we are considered as in other materials it can be

ze holds holds are considered as opposed to which charges but anyway here is this battery having a terminal

with a high post of charges and another negative charge.

So what does ze negative charges would like to do that negative charges would like to go from here and

go to ze positive particles.

Okay.

As you know that for example ze magnet ze magnet ze negative charges are attracted to ze positive charges.

Okay.

Or ze positive polarity attracted to the negative polarity but ze positive and the positive are repulsion

was each also so anyway as the negative charges or negative electrons would like to go here OK.

Until going through here.

So is this electrons.

Is ze one which forms our electric current which you are going to discuss in sensitivity.

So ze charges here which are flaws here causes ze electric current and the cause is this electrical

load to be operated.

OK.

So the benefit here of electrical charges which is representing our electron is that as we are following

the from the terminal through C load and to the other terminal.

OK.

So that is a benefit of electric charges and considering easy electricity and the electron one electron

equal to this value of column.

So if we have one coolant Zain we will have a one over one point six multiplied by ten point negative

19 electrons which is this number of electrons.

So this number of electrons representing one column.

Okay.

So under sends out one column is considered as a very large value.

So in actual life the value of the charges are in the order of.

And B call column or nano Nano which is then borne negative 9 which we discuss the Easy As on units

and typical is ten pound negative twelve.

So this is the actual value of our column or our electrons.
