@nelsonrochaa,

Thanks for the clarification. Consider this:


"Ørsted discovered the connection between magnetism and electric current when a magnetic field produced by a current-carrying copper bar deflected a magnetised needle during a lecture demonstration".


"In the CGS system, the unit of the H-field is the oersted and the unit of the B‑field is the gauss. In the SI system, the unit ampere per meter (A/m), which is equivalent to newton/weber, is used for the H‑field and the unit of tesla is used for the B‑field".

"H is measured in units of amperes per meter (symbol: A⋅m−1 or A/m) in the SI. B is measured in teslas (symbol: T)".


This is what you need to understand: The H field is an electrical equivalent and the B field a magnetic one.

Hi synchro1,
I just try show you that are some type of misunderstood between you and TK in relation to that theme of definition of what is  W and Wh
nothing more . what TK refers is what is agreed and write in actual conventional laws.

I know what is H field and a B field i have a meter do measure that values and you have right about that point .
Thanks

gauss tesla (T) 0.0001 weber/sq.metre tesla (T) 1 ampere-hour coulomb (C) 3,600

1 Coulomb= 1 Gauss

1 Watt Hour= 1 Tesla.

A negative number multiplied by a positive integer can only yield numbers of a negative value. Like the negative one for exponent to the right and above the "H".

I was just interpreting what I think Nelson was saying. watt is a watt, and the difference between the Wh and W according to nelson they are the same just read over different periods of time. So it is like saying that the Kg is not the same as mg in a way.

No, the watt is a _rate_ and the watt-hour is a _quantity_. The watt is a rate of energy of one Joule per second passing a measurement point -- Like a mile per hour, it is a rate of "things" passing a measurement point in a unit of time. The watt-hour is a quantity, like miles is a quantity of distance, or what you read on the odometer, not the speedometer. Joules/second (watt) multiplied by time (seconds, hours whatever) gives you a quantity, a number of joules. 

They are not the same thing by any means, and this is most certainly NOT like saying the Kg is not the same as the mg. It is like saying the mile per hour is not the same thing as the mile.

I suppose you would have to average them out. Id say as long as you have at least 1 full ac cycle that the average should equate to that fraction of an hour if it were measured in 1 sec. If in 1 sec you only measured 1/4 wave of the ac cycle, that would not give an accurate depiction of power used over a longer period of time. Thus the Wh?

Now you are getting all tangled up. Yes, to calculate or measure the number of Joules in a given time interval, you look at the power (watts, joules per second) and multiply that by the time involved (fractions of a second, days, weeks, whatever, reduced to seconds). Joules/second times seconds = joules. It's basic algebra!
The "Watt-hour"  means watts x time and results in an answer in joules. (Joules/second) x (seconds/minute) x (minutes/hour) = Joules !!  Algebra! The time units cancel and leave you with only joules, a _quantity_. Not a _rate_ like watt.

Wrong three times in one little post.

1 coulomb is not one gauss -- that is why they have different names, BECAUSE THEY ARE NOT THE SAME THING. One watt-hour is not 1 tesla, and

a negative exponent means INVERSE, not "negative value".  X^-1 equals 1/X, not some "negative value". Basic algebra !!
