Question 1.
What does biasing a BJT do?
Show hintHide hint
Think about the role of a transistor in amplification.
Question 2.
Define the term I-V Characteristic.
Show hintHide hint
What graphically represents current against voltage fluctuations?
3Question 3.
What is the primary function of biasing in BJTs?
- To amplify signals
- To set the operating point
- To improve efficiency
Show hintHide hint
Consider how biasing affects operational states.
4Question 4.
In which condition does a BJT operate as an amplifier?
- True
- False
Show hintHide hint
Recall the active region characteristics.
Question 5.
A circuit uses a BJT in an amplifier configuration. If V_BE is measured to be 0.7 V and the base current is 20 μA, calculate the expected collector current given β = 150.
Show hintHide hint
Use the current gain formula for BJTs.
Question 6.
Design a circuit with a BJT where you need to achieve a collector current of 5 mA. If your desired β is 200, what should be the base current?
Show hintHide hint
Apply the formula that relates collector current and base current.
