Question

bio junction transistor draw the symbol​

Answer 1

$\huge\underline\green{\mathcal Answer :-}$

A bipolar junction transistor (bipolar transistor or BJT) is a type of transistor that uses both electrons and holes as charge carriers.

Unipolar transistors, such as field-effect transistors, only use one kind of charge carrier. BJTs use two junctions between two semiconductor types, n-type and p-type.

BJTs are manufactured in two types: NPN and PNP, and are available as individual components, or fabricated in integrated circuits, often in large numbers.
