Question

what is the major difference between bipolar and unipolar device explain with example​

Answer 1

Answer:

transistors can have both minority and majority carriers flowing, whereas FET's only have majority carriers flowing. The fact that bipolar transistors have two types of carriers flowing simultaneously results in the name 'bi-polar'.

As their name implies, Bipolar Transistors are “Bipolar” devices because they operate with both types of charge carriers, Holes and Electrons. The Field Effect Transistor on the other hand is a “Unipolar” device that depends only on the conduction of electrons (N-channel) or holes (P-channel).

Answer 2

Answer:

• Field-Effect Transistor (FET) - A three-ended (three electrodes), voltage-controlled semiconductor electronic component that has the ability to amplify an electrical signal.
• The FET family is made up of several different types of components that all have one thing in common: the indirect effect of the electric field on the semiconductor resistance or the resistance of the thin, non-conductive layer.
• The Bipolar Junction Transistor is a type of semiconductor that can be used for switching or amplification.
• Bipolar Transistors, as the name implies, are "Bipolar" devices because they use both types of charge carriers, Holes and Electrons. The Field Effect Transistor, on the other hand, is a "Unipolar" device that relies solely on electron (N-channel) or hole conduction (P-channel).
