6 sample questions

Question 1.
What does BJT stand for?
Show hintHide hint
Think about the type of transistor.
Question 2.
Explain the significance of V_BE(on).
Show hintHide hint
Consider the forward bias condition.
3Question 3.
What is the relationship between the collector current (IC) and base current (IB) in a BJT?
- IC = β × IB
- IC + IB = β
- IC - IB = β
Show hintHide hint
Think of the current gain concept!
4Question 4.
True or False: The piecewise linear model complicates the analysis of diodes.
- True
- False
Show hintHide hint
How does it impact calculations?
Question 5.
Given a BJT with β = 120 and IB = 2 mA, if a load resistor of 1 kΩ is connected to the collector, calculate the operating point both theoretically and using numerical methods.
Show hintHide hint
Start with finding IC then use Ohm's law for the voltage.
Question 6.
A BJT shows unpredictable output currents under varying input conditions; analyze what might be wrong with the biasing configuration.
Show hintHide hint
Think about what happens if V_BE is too low.
