The device
converts
thermal energy
to
electrical energy and vice versa, via the Seebeck
effect.
Immerse the metal plates in two different temperature
baths. Unit
will
generate 10mV/degree temperature difference. Show this
with a
multimeter
or use it to run a small fan.
To show the reverse
effect, connect
jacks
to
a low voltage power supply and plates will become different
temperatures.
NOTES
Provide a beaker full of boiling water and a beaker of ice
water.
