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.

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.

Nice explanation
I think is completely and clear about this subject.
Thanks

Nelson, I'm glad we agree on this basic algebra.

And now we are beginning to see where synchro has gone off the rails. He clearly doesn't get that the Inverse is not the Negative. X^-1 is equal to 1/X, not some negative value. And the H (scalar unit of induction) of the Henry is not the same as the  H (vector quantity)of the magnetizing field strength. He apparently has confused these two very different things in his mind, because of the use of the same letter for both. But the H of the field strength is a letter chosen at random by Lord Kelvin in 1850, and has nothing to do with the assignment of the name Henry and the letter H as abbreviation for the unit of inductance.

For Synchro: When letters are Bolded like that it is not done for emphasis. It is a common way to indicate that the quantity referred to is a _vector_ not a scalar. But I don't expect you to understand the difference, since the math is obviously over your head. You should however be capable of clearly understanding that the "H" of inductance is not the same thing as the "H" of magnetic field strength. Or am I giving you too much credit?

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 !!

@Tinselkoala,


Look again for the equal signs!


The negative Henry is the same as the Inverse Henry. Why don't you try and calm down?

@Tinselkoala,


You have been unflatterinly compared to "Thamsanqa Jantjie", Barack O'bama's fake deaf sign interrurpreter. When are you gonna knock the childlike antics off and settle down and act nice?

I see knobody will answer my earlier questions so far, so Ill pose them again...

If we have a 100t tbf coil and we apply 100v dc, how long would it take for there to be 50v between all pairs of adjacent turns in the coil and what criteria do you consider determines the given answer, if it is ever given a shot.

Would one say that the 50v would be there between each turn only after the inductor has reached full current?
