Question 1.
What is the main difference between n-p-n and p-n-p transistors?
Show hintHide hint
Think about the layering order.
Question 2.
What happens to current flow when a transistor is reverse biased?
Show hintHide hint
Consider the direction of voltage application.
3Question 3.
What junction in an n-p-n transistor must be forward biased for operation?
- Base-Collector
- Base-Emitter
- Emitter-Collector
Show hintHide hint
Remember the arrangement of the junctions.
4Question 4.
In which quadrant does the I-V characteristic of a p-n-p transistor appear?
- True (First Quadrant)
- False (Third Quadrant)
Show hintHide hint
Consider the signs of currents and voltages.
Question 5.
Design a simple circuit with a p-n-p transistor to amplify a low-level audio signal. What biasing arrangement would you use, and what calculations are required?
Show hintHide hint
Focus on maintaining V_EB and V_EC.
Question 6.
Given the current gains and the saturation values for both n-p-n and p-n-p transistors, calculate the expected collector current for a given base current. Discuss how the differences in design affect performance.
Show hintHide hint
Consider practical limits of each type.
