Coanda effect

Hi Walt. I have replied to your question about water flowing down the back of a spoon. You will find my answer immediately after your question at Talk:Fluid dynamics Regards. Dolphin51 (talk) 22:06, 26 January 2009 (UTC)[reply]

Ceramic heating elements

I'll try to explain how ceramic heating elements work as best I can. The general principle, used by all heating elements, is called resistive, or Joule, heating. When an electrical current is applied to a conductor with high resistance, the electrons will transfer some of their kinetic energy to the conductor. This is observed as an increase in temperature.

Most ceramics, such as porcelain and glass, are insulators at room temperature. With the application of heat to a ceramic, charge carriers become available, making it electrically conductive. Metals show opposite behavior, and will increase in resistivity when heated. --TDogg310 (talk) 21:40, 18 June 2009 (UTC)[reply]

With more charge carriers in a conductor, there will be more collisions between the electrons and the conductor, and subsequently additional kinetic energy will be converted into heat. I wish I could elaborate, but my ceramics textbook mostly covers the manufacture and usage of heating elements, not their underlying principles. The relationship between heat, current, and charge carriers seems paradoxical even to me.

Despite what my talk page may imply, I do not reside in the state of Hawaiʻi. I have, however, visited the islands on several occasions. I began editing articles related to their flora and fauna after seeing a commercial encouraging viewers to vacation in Hawaiʻi, which I felt was using false advertising. --TDogg310 (talk) 23:17, 18 June 2009 (UTC)[reply]
