BJT vs. FET Fundamentals

medium 10 Questions
Question 1 of 10

What does BJT stand for?

BJT stands for Bipolar Junction Transistor.
Question 2 of 10

What is the primary charge carrier type(s) in a BJT?

BJTs utilize both electrons and holes as charge carriers.
Question 3 of 10

What does FET stand for?

FET stands for Field Effect Transistor.
Question 4 of 10

What is the primary charge carrier type(s) in a FET?

FETs primarily use one type of charge carrier (either electrons or holes), making them unipolar devices.
Question 5 of 10

Which terminal in a BJT is the middle layer and typically the most lightly doped?

The base is the middle layer in a BJT and is lightly doped.
Question 6 of 10

Which terminals in a FET control the current flow?

The voltage applied to the gate controls the current flow between the drain and source in a FET.
Question 7 of 10

Which type of transistor is considered a voltage-controlled current device?

FETs are voltage-controlled devices where the gate voltage controls the drain current.
Question 8 of 10

Which type of transistor is considered a current-controlled current device?

In a BJT, the base current controls the collector current.
Question 9 of 10

In which region does a BJT act as an amplifier?

The active region is the operating region for a BJT acting as an amplifier.
Question 10 of 10

Compared to a BJT, FETs generally have a:

FETs have a very high input impedance.
