Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What happens to the base width (W_B) when the collector voltage (V_CE) increases?
💡 Hint: Think about the relationship between voltage and the depletion region.
Question 2
Easy
Define beta (β) in relation to collector current.
💡 Hint: Remember, it's a measure of how effectively a transistor can amplify current.

Challenge Problems
Push your limits with challenges.
Question 1
If a transistor operates with a constant collector voltage of 5V, and the base width is originally 0.5 μm, predict the implications if V_CE is increased to 7V.
💡 Hint: Reflect on how base width changes with voltage.
Question 2
Design a simple BJT circuit that ensures the collector current does not exceed 10 mA, considering varying V_CE values. Outline the parameters you will monitor.
💡 Hint: Think about how resistors control current flow.
