Well... after spending many hours reading various opinions on the topic... I am bemused to admit once again Wikipedia provided the explanation that provided the most help for my purpose. I am repeatedly astonished that this one source of information keeps popping up as the place I find answers...

Polaris-1, excellent! I have not read anything along the lines of your explanation. I've Googled "vector" with various electrical terminology and I think this is by far the most helpful explanation provided. Your approach definitely provides me a way to do some research and gain a better...

Phinds, you make a valid point. I think I see individuals are very adept at memorizing terminology and equations who really don't understand the science behind it... for the very unfortunate reason that all the memorization work doesn't leave time to actually understand the science. I know...

I don't understand.. Are you saying Joules is not: J = kg * m**2 / s**2 a ratio of mass and distance to time? And also, I apologize... but why is ten squared dollars not dollars?

Wow... seconds squared is not seconds? I'm sorry... but, that is beyond my understanding. And yes, absolutely... Coulombs is not directly related to Joules. Coulombs is a quantity of charge from a specific quantity of electrons. Joules is mass moving a distance over a period of time...

https://en.wikipedia.org/wiki/Joule J = kg * m**2 / s**2 s = seconds Joules is a very important unit of measurement. I can't think of a simpler way to express an unit of energy as equal to moving a unit of mass over a unit of distance within a unit of time.

M Quack, yes you make an excellent point. I unfortunately live in a country not using the metric system. Dealing with human nature is problematic. But, I would hope scientists could be more rational. I would hope the community would help push everyone to more logical units of measure such as...

M Quack, First, as you demonstrate in the equations you provide, they are redundant ratios of the same thing. Second, all of the equations you provide are expressing a quantity of electrons within a time period. They provide no useful purpose. Electrons per second is sufficient for any and...

M Quack... a Volt is 1 Joule divided by 1 Coulomb. A Joule is a ratio involving time. I think Joule is an excellent concept... as good as (but completely unrelated to) Coulomb. I still think amps, watts and volts are a waste of time.

M Quack, thanks for your reply. I must respectfully refute your assertion. Joules is a ratio of mass, distance and time. It is not directly related to charge (i.e. coulombs) which is measured in a quantity of electrons. You do bring up a good issue. There is probably an interesting...

SteamKing, thanks for your reply. With all due respect I must disagree with your comments. I'll just point out one thing to better make my point. Voltage is not analogous to pressure. Voltage is a ratio involving a quantity of electrons over time. Pressure does not include a time element.

Drakkith, thanks for the reply. Sorry, but I disagree with your comments. Amps, volts and watts are all ratios of electrons per unit of time. They are useless and redundant concepts. Coulombs is not a ratio... it is a specific number of electrons. It is simpler and more clear to say...

Thanks Russ, and yes... that's my point... amperes is coulombs per second. Why make up all this useless terminology. I see countless amounts of time on the internet wasted where individuals are struggling to understand useless, redundant terminology. I think it would not be so bad if each...

I've been trying to brush up on my electrical engineering skills and have been working on the circular and redundant terminology of amps, volt, ohms and watts. It seems to me it all comes down to a quantity of electrons (i.e. coulombs). And, for various reasons perhaps the number of electrons...
