for amplification and switching applications.

Thermistor is a device in which the resistance is varies
with the temperature variation. they are used to protect the
electrical machines / windings by sensing temperature. these
are made up of metal oxides. they are non linear in nature.

Thyristor is 3 terminal 4 layer semi conductor device used
for switching applications.
