Practice Questions

Test your understanding with targeted questions

Question 1 Easy

What does it mean when we say a junction is forward-biased?

💡 Hint: Think about which side is 'charged' more positively.

Question 2 Easy

Name the two types of carriers in a BJT.

💡 Hint: One type is present in p-type material while the other is in n-type material.

Quick quizzes to reinforce your learning

Question 1

Which condition allows current to flow from the emitter to the base in a BJT?

Reverse Bias
Forward Bias
Cutoff

💡 Hint: Think about how the positive charge affects current flow.

Question 2

True or False: Minority carriers are present in larger concentrations than majority carriers in a BJT.

True
False

💡 Hint: Think about the definitions of majority vs. minority carriers.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If a BJT's base-emitter voltage is increased from 0.2V to 0.7V, describe the change in current flow in the junction.

💡 Hint: Recall how voltage and current are related in a diode.

Challenge 2 Hard

A BJT is operating at a temperature of 60°C and the intrinsic carrier concentration doubles. How does this impact the minority carrier concentration?

💡 Hint: Think about the impact of temperature on carrier dynamics.
