Transistor is 3 terminal 3 layer semi conductor device used
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.

what is the benefit of floating our DC source? if i have two floating DC source of which 1 has a ref voltage of -21VDC and the other of -18VDC. can it be connected in parallel to share a common ref voltage? if not, how do i make both sources to be of common ref voltage? tks
