Which of the following is unipolar transistor?

p-n-p transistor

n-p-n transistor

Field effect transistor

Point contact transistor

Solution

Field effect transistor

In Field effect Transistor ( FET ) there is only one type of charge for conduction from drain to source i.e either electrons ( n-channel FET ) or holes (P-channel FET).

In NPN and PNP transistor both electron and holes take part in conduction. Hence they are bipolar Junction Transistor.

Point contact Transistor is also Bipolar Junction Transistor.
