Transistor:it s a three terminal device which is used in
amplification process whereas diodes can be used in
rectifiers for conversion of ac to dc source.
Diode is a two terminal device,with no amplification taking
inside only act as a switch with low speed while transistor
can be used for high speed switching transients.....
Diode is used for simple application.....for rectification
of Ac current to DC...
Transistor is a modified form of diode. Transistor has 2
diodes. It is used for amplification, switching and more
