Bipolar and unipolar transistors can be categorized according to their basic functionality. In bipolar transistor the electric current flows due to BOTH electrons and holes through it. However, in unipolar transistor the current flows EITHER due to electrons OR holes through it.
Read MoreIntroduction to Bipolar & Unipolar TransistorsUJT has one PN junction with two internal resistances Rb1 and Rb2 such that Rb1 is the internal resistance between base-1 and emitter. And Rb2 is the internal resistance between base-2 and emitter.
Read MoreConstruction of Uni Junction Transistor (UJT)The Junction Field Effect Transistor consists of one long n-channel with two p-layers inserted at the sides. The n-channel forms the conducting path for the charges.
