Rosemary:

Most of the time when you are talking about power you actually mean energy.  And you hung yourself.  This was another heart-sinking moment.

However, there is a silver lining here.  You actually have mastered Watts and Joules and do understand, we just need to run the translator in our heads.

ACTUALLY -  POWER AND ENERGY ARE SYNONYMOUS.  It is just that the term power is appropriate to the computation of electric energy - as a rule.  The one term is entirely interchangeable with the other.  Check it out.  Look it up.  Do with this information what you please.  Hopefully it won't bring on a heart attack.

Not actually mrsean.  When I refer to watts per second it is in the context of computing JOULES.  There is NO OTHER WAY TO COMPUTE THOSE JOULES.  The calculation of WATTS is described in my post to you which you clearly CANNOT answer.

You are incorrect in every important respect.


Watts per second is a meaningless phrase, outside the definition which I handed to you on a plate, and which you've misunderstood. It is either "Watt seconds" or "Joules" if you are talking about energy, or "Joules per second" or "Watts" if  you are talking about power.


Power and energy are not interchangeable in the way you keep stating. In the same way that "gallons of petrol" and "miles per gallon" are not interchangeable.


I wasn't aware there was a question in your post.

power = watts
energy = joules

You understand watts and joules and you know that they are not interchangeable.  Therefore from above you can see that power and energy are not interchangeable.  You simply had the wrong vision in your mind as to what power and energy mean.

I think I'm beginning to get GL's humor now. For example in that post where he actually did the derivation, the last part of his algebra went like this:

QuoteW = Coulomb/s * J/Coulomb gives W = J*s

Clearly....  Coulombs/seconds * Joules/Coulomb == (Coulombs*Joules)/(seconds*Coulomb). Right? So the Coulomb term cancels and we are left with the answer: W = Joules / second which in spoken English is said "Joules per second".

X/s * Y/X will always result in Y/s...... not Y*s. So by doing the derivation he came up with the right answer and sarcastically illustrated the absurdity of the wrong one by showing it is a mathematical contradiction.

I want to thank you both, GL and mrSean, for participating in this discussion and I commend GL for his intellectual honesty and his striving for knowledge. Good work, gentlemen.
