14.1.3. Overview of Discussion

Try these first

1. 1.

   What does BJT stand for?

   Hint

   Think about the type of semiconductor device.

2. 2.

   What is the primary function of a BJT?

   Hint

   Consider its role in circuit design.

3. 3.

   What is the main role of a BJT in circuits?

   • To resist current
   • To act as a switch
   • To amplify signals

   Hint

   Consider its fundamental purpose.

4. 4.

   True or False: The collector current of a BJT is linearly dependent on the base-emitter voltage.

   • True
   • False

   Hint

   Review the principle of BJT operation.

5. 5.

   Given a BJT in a common emitter configuration with a base current of 12 µA and a current gain of 150, determine the expected collector current.

   Hint

   Focus on the multiplication of two current values.

6. 6.

   If the collector-emitter voltage drop is 5V across a BJT, and the collector current is calculated to be 2 mA, determine the resistor value connected to the collector if the voltage supply is 12V.

   Hint

   Recognize that the total supply voltage must account for voltage drops across the resistor.
