6 sample questions

Question 1.
What is the formula to calculate base current (I_B) given collector current (I_C) and beta (β)?
Show hintHide hint
Think about how both currents are related through beta.
Question 2.
What does the parameter alpha (α) represent in a transistor?
Show hintHide hint
Remember the relationship with emitter current.
3Question 3.
What is the relationship between collector current (I_C) and base current (I_B)?
- I_B = I_C * β
- I_B = I_C / β
- I_B = I_C + β
Show hintHide hint
Think of β as a scaling factor for the currents.
4Question 4.
Increasing the collector voltage (V_CB) always decreases the collector current (I_C).
- True
- False
Show hintHide hint
Consider what happens to the base width with varying V_CB.
Question 5.
A BJT has a beta of 200. If the base current is 0.01 mA, calculate the collector current.
Show hintHide hint
Use the relationship between I_B and I_C to solve.
Question 6.
Explain how modifying the voltage V_CB affects both W_B and I_C in a practical circuit application.
Show hintHide hint
Think about how both voltage and the dimensions interact in the circuit.
