14.1.9. Finding Collector Current

Try these first

1. 1.

   Define base current in relation to collector current.

   Hint

   Recall the relationship

2. 2.

   A BJT is configured in the common emitter configuration with a base voltage of 0.7V. What is the expected state?

   Hint

   Check the conditions for active regions.

3. 3.

   True or False: The collector current is independent of base current.

   • True
   • False

   Hint

   Refer to the formula relating

4. 4.

   Determine the collector-emitter voltage and collector current for a BJT with V_{CC} = 15V , R_C = 1kΩ , and I_B = 20μA , considering β = 100.

   Hint

   Apply KVL for the circuit loop to find V_{CE}.

5. 5.

   Design a biasing network for a given BJT to achieve a stable operation at I_C = 5mA with fluctuations in V_{CC} .

   Hint

   Consider the voltage divider rule and how it affects the base current.
