Question 1.
What are the three regions of a BJT?
Show hintHide hint
Think about the layers of the transistor.
Question 2.
What happens to a BJT when the base-emitter junction is forward biased?
Show hintHide hint
Consider what forward bias means.
3Question 3.
What happens to current in a BJT when the base-emitter junction is forward biased?
- Current flows
- Current is blocked
- Voltage drops
Show hintHide hint
Recall the meaning of forward bias.
4Question 4.
Is it true that reverse bias prevents current flow in the base-collector junction?
- True
- False
Show hintHide hint
Think about what reverse bias means.
Question 5.
Given a BJT operation with a forward bias of 0.7V, calculate the expected collector current assuming I0 = 0.01 mA and V_T = 25mV.
Show hintHide hint
Use the exponential relationship in the current equation.
Question 6.
Discuss how varying the base-collector potential while keeping base-emitter bias constant influences the overall BJT operation.
Show hintHide hint
Think about how reverse bias modifications affect charge flow.
