What Is a Volt? Explaining Watt & Energy Measurement

[chroot]

JohnDubYa,

Are you simply trying to impress upon rayjohn01 that the value of the potential is arbitrary (since you are free to select your zero anywhere you like) and only differences in potential matter?

rayjohn,

It should be clear that many people here have quite a bit more education in physics than what you got for your BSEE.

Absolutely incorrect.

1 watt = 1 joule per second, where the joule is a unit of energy.

The "watt per hour" is, shall we say, a unit you don't come across often unless the power in some circuit is changing.

You may be confusing your terms with the watt-hour (NOT watt/hour) which is the energy delivered by one watt of power over 3600 seconds, or 3600 joules.

O.K. The bucket analogy sucks...

To John ,you are telling me that no work is done on a mass which falls from your hand to the Earth ( kinetic) and that no work is done by lifting it from the ground upward (potential) -- that's nonsense and you know it.

The work done on WHAT?

Here is what you posted earlier.

In both cases the word potential has been abreviated ( leaving out it's origin ) which the work done by a TEST object ( mass in above) approaching the one in question.

"...the work done by a test object. On what? The Earth? If so, I have illustrated why this definition is absurd. If the work is being done by the test object, upon which body is the test object performing work on? You have yet to answer the question.

I took university physics for 4 years with electrical and electronic engineering and I'm afraid your intuitive idea of what potential stands for is in error. Not only that but you cannot define how to measure it.[/b]

Well, with t-h-o-s-e credentials how could I possibly disagree? I mean, what would I know in comparison to someone who has had four years of electrical engineering?

If we cannot agree let's call it quits since it not getting either of us anywhere.

It isn't that we differ in opinion. You are simply wrong.
