Question 1.
What is V_BE in a BJT?
Show hintHide hint
Think about the threshold voltage needed for conduction.
Question 2.
What does collector current (I_C) signify?
Show hintHide hint
Consider its role in the transistor's functionality.
3Question 3.
What is the primary function of V_BE in a BJT?
- Forward biasing the base-emitter junction
- Determining collector current
- Regulating output voltage
Show hintHide hint
Think about the role of a battery in a circuit.
4Question 4.
As you increase the input voltage, what happens to the collector current?
- True
- False
Show hintHide hint
Consider the direct relationship between I_B and I_C.
Question 5.
Design a common emitter amplifier circuit that has a target current gain (β) of 150. If the input voltage is adjusted from 0.5V to 1.5V, calculate the expected change in collector current. Assume all other conditions remain constant.
Show hintHide hint
Analyze the input-output dynamics based on the assumed voltage characteristics.
Question 6.
You have a BJT with an unknown β, and you notice that the collector current is 10mA with a base current of 100µA. If you increase the base current to 200µA, what is the expected collector current change if the BJT is operated in active region?
Show hintHide hint
The proportionality relationship of base to collector current is key here.
