Question 1.
Define a BJT.
Show hintHide hint
Think of how BJTs are categorized.
Question 2.
What does the β (Beta) represent in BJTs?
Show hintHide hint
Consider the relationship between input and output currents.
3Question 3.
What does β represent in a BJT?
- Current gain
- Voltage gain
- Power gain
Show hintHide hint
Remember it’s related to current ratios.
4Question 4.
True or False: The I-V characteristics of all BJTs are identical regardless of type.
- True
- False
Show hintHide hint
Think about the configuration of the transistors.
Question 5.
Design a circuit using an n-p-n transistor model where β=100, and I_B is set to 0.1 mA. Evaluate I_C and determine the collector-emitter voltage drop if it is 10V.
Show hintHide hint
Start with applying the formula for current gain, and evaluate the drop accordingly.
Question 6.
If a p-n-p transistor has a β of 30 and an emitter current (I_E) of 15 mA, calculate the base current (I_B) and collector current (I_C).
Show hintHide hint
Use relationships among I_C, I_B, and I_E to solve.
