Question 1.
What does I-V characteristics refer to in BJTs?
Show hintHide hint
Think about how current changes with voltage.
Question 2.
What is the role of B2 (Beta) in a BJT?
Show hintHide hint
It shows how much the base current is amplified to produce collector current.
3Question 3.
What does B2 represent in a BJT?
- Resistance
- Current Gain
- Voltage Level
Show hintHide hint
Remember, it's associated with how much current is amplified.
4Question 4.
True or False: PNP transistors use electrons as majority charge carriers.
- True
- False
Show hintHide hint
Think about the naming convention for both types.
Question 5.
A BJT has a beta (B2) of 150. If the base current is 20μA, calculate the collector current.
Show hintHide hint
Apply the current gain formula.
Question 6.
Given a PNP transistor in a circuit, if the V_BE is 0.7V leading to a collector current of 2mA, explain how changing the temperature might affect the characteristic graph.
Show hintHide hint
Links between temperature effects and current flow should guide your explanation.
