Peltier Effect: Cooling & Thermoelectricity

[navneet1990]

It occurs when a current is passed through two dissimilar metals or semiconductors (n-type and p-type) that are connected to each other at two junctions (Peltier junctions). The current drives a transfer of heat from one junction to the other: one junction cools off while the other heats up; as a result, the effect is often used for thermoelectric cooling.

can it be possible
that we heat on ened
thus cool the other and thus producing electricity??
i need urgent answers
thanyu for your co-operation

Yep. Works both ways.

And the inverse phenomenon is called the Seebeck Effect.

 

[navneet1990]

could you please elaborate on how it works both way
can an experiment be performed to prove this?

You could try looking http://www.peltier-info.com/
The experiments are simple enough that you could do them yourself.

Heard of a thermocouple?

 

[navneet1990]

yes
thermocouples
but i don't really know much about them
could you tell me
examples

We've given you lots of keywords. Have you tried Googling anyone of them?

If you have a specific question about something you don't understand from all your reading, we can help clarify your doubt. If you need help with being pointed to good references aimed at a particular level, we could do that too. If you want us to write up treatises on subjects that you haven't put the effort of researching yourself, you'll find very little help.

i did search and see and obtain all the inoformation
thank you
