Answer / starlin

A unijunction transistor (UJT) is an electronic
semiconductor device that has only one junction. The UJT
has three terminals: an emitter (E) and two bases (B1 and
B2).

UJT is a three terminal device.one is emitter and two are
base terminals it is used as a relaxation oscillator

Answer / hervinder

basically ujt is unipolar transistor and it is three
terminal device and normally used in relaxation transistor

Answer / c.kumaresan

A unijunction transistor (UJT) is an electronic
semiconductor device that has only one junction. The UJT
has three terminals: an emitter (E) and two bases (B1 and
B2). The base is formed by lightly doped n-type bar of
silicon. Two ohmic contacts B1 and B2 are attached. A
voltage-controlled switch that controls current.
