Is this a correct definition of one volt using electric potential energy per unit charge?

Hi guys! Just a quick question here, it should be simple enough but every time I derive something I'm very skeptical of its validity. Anyway, here it is:

One volt is when:
The difference in (electrical potential energy per unit charge (q)) between two places equals one.

Where electrical potential energy equals

(EPE at distance R from charge Q) = (1/4piEpsilonNought) * Q/R

Where the source charge Q is a spherical object in a vacuum.
If the source charge is a different shape the definition still holds but the equation for the EPE will be different.

Is this correct?

Thanks!

This statement is correct

Electrical potential can be measured in Joules per Coulomb which has been defined as a volt.

1 joule per coulomb = 1 volt = 1V

You can also define Volts as as follows but more concerened with electrostatic charge
Electrostatics
Force = KQqR2 Force between two charges Coulombs law

V = kq/r


k is the constant (approx) 9x10^9 Nm^2/C^2 it's also related to epsilon_0 (epsilon_0 is that funny looking E), permittivity of free space.. Epsilon sub 0 = 1/4pik = 8.8542E-12 C^2/N*m^2.
E is electric field, in newtons per coulom

If you want more explanations on this This is long time ago stuff this back to the science classrooms at school my memory isnt that great anymore Freeman was so boring I had to sleep in class It was all you could do in his class He wasnt impressed neither were my parents, or the headmaster at the time , but still there you go such is life

I think his lessons only became interesting when he pulled out the Van der Graaf Generator and the Maltese cross tube plus of course the induction coil


We used to call this deigos cross for some reason perhaps Im confused

Thats that tube that projects a cross onto the phosphur screen which we used to play with The litheum was good and the potasium was cool because we used to nick the stuff out of the science class and throw it on the swimming pool

That was great fun

No we never got caught lol


Here is a website for you to explain more

So yes Its true

Thank you very much that has helped a lot!
And I know exactly what you mean with boring lecturers, I have experienced similar classes
electromagnetism is a fun topic though.

hi Craig Hickman. i'm not an engineer or a scientist but i'm an electrician. and though i'm not a master of my field but just reading the steps or explanations that you've made, already make me realize that it's absolutely correct. i mean i've been practicing actual electrical works and i also know some of the terms. besides, it was also being verified by Mark Harrington as correct. well, keep up the good work and i know many well be inspired by your thoughts. cheers.
