Explain the construction and bipolar junction transistor (BJT). [5]
A Bipolar Junction Transistor (BJT) is a three-terminal semiconductor device formed by combining two PN junctions in a specific manner. It is called "bipolar" because its operation involves both types of charge carriers -- holes and electrons. --- A BJT consists of three alternately doped semicon...
