Questions and Answers

What are the leads labeled as in a bipolar junction transistor?

E, C, and B for emitter, collector, and base

P, N, and P for positive, negative, and positive

A, B, and C for anode, base, and cathode

E, B, and C for emitter, base, and collector (correct)

Why are the emitter and collector regions not interchangeable in a BJT?

Due to the difference in doping levels (correct)

Because they are physically identical

Due to their interchangeable nature

Because they have the same doping level

What is the bias condition for the base-emitter (BE) junction in a BJT operating as an amplifier?

Unbiased

Reverse-biased

Short-circuited

Forward-biased (correct)

How does the operation of a pnp transistor differ from that of an npn transistor?

<p>The roles of the electrons and holes, the bias voltage polarities, and the current directions are all reversed</p> Signup and view all the answers

What type of bias arrangement is used for both npn and pnp BJTs for operation as an amplifier?

<p>The base-emitter (BE) junction is forward-biased and the base-collector (BC) junction is reverse-biased</p> Signup and view all the answers
