14.1.11. Generalized Procedure for Finding V_CE

Try these first

1. 1.

   What does V_CE represent in a BJT circuit?

   Hint

   Think about the terminals involved.

2. 2.

   Define I_B.

   Hint

   It's the current that activates the BJT.

3. 3.

   What is the relationship between I_B and I_C?

   • I_C = I_B
   • I_C = β * I_B
   • I_C = I_B / β

   Hint

   Recall the definition of β.

4. 4.

   KCL ensures that what happens at a junction?

   • True
   • False

   Hint

   Think about current flow directions.

5. 5.

   Given a BJT circuit with V_CC = 12V, R_C = 1kΩ, determine V_CE if I_C = 0.015A.

   Hint

   Use the voltage drop calculation carefully.

6. 6.

   In a circuit with a base resistor of 220Ω and a voltage of 5V at the base of a BJT, calculate the base current I_B assuming V_BE = 0.7V.

   Hint

   Use Ohm’s law for your calculations.
