@Tinsel Koala
Thank you for keeping the conversation relevent and on topic.
@Dr.Stiffler
I agree with the last part, and on that note I will take my leave from here and let you gentlemen carry on with the business at hand.
@All
Now back to business, Rosemary Ainslie states there is extra heat showing up relative to the power input. Irregardless of anything stated we can conclude this heat is generated in the wire wound resistor or certain elements of it. We can also guess that this resistive/inductive heating effect is due to transient energy as she stated. Of the many possibilities it should also be considered that the heating effect could in fact be "inductive" heating. It is well know that modern oven cooking surfaces use inductive heating effects, that is a coil under a glass top will induce currents in any metallic pot or pan above it, this heats the metal but not the glass top. If Rosemary Ainslie's wire wound resistor was ceramic with metallic components and these metals were particulate and evenly dispersed then there is the possibility of micro-currents developing within the metals due to induction at high frequency. These micro-currents usually refered to as eddy currents may not produce aggregate fields as we are familiar with thus could easily go unnoticed.The wire could be considered the "emitter" the particulate metals the "reciever". In any case there are many things which may be taken for granted initially which may hold relevence. Many materials have very different properties when high frequency/high potential currents are involved.

Accurately and professionally stated, except you left out the second book on thermodynamics and how to properly construct, calibrate and interpret a calorimetry. I'm now 1000% sure this could take years the way tis thread has digressed, I would think it time for for someone to put a stop to it or it has become just another beat my chest forum.
