9.1.5. Equation Modifications for PNP

Try these first

1. 1.

   What are the three regions in a PNP transistor?

   Hint

   Think about the arrangement of types.

2. 2.

   What condition must the base-emitter junction satisfy for a PNP?

   Hint

   Is the emitter voltage higher or lower than the base?

3. 3.

   What is the correct biasing requirement for the base-emitter junction of a PNP transistor?

   • Forward-bias
   • Reverse-bias
   • No bias

   Hint

   Think about what condition allows currents to flow uninterrupted.

4. 4.

   In a PNP transistor, which terminal has the highest voltage?

   • True
   • False

   Hint

   Recall the biasing configuration.

5. 5.

   Calculate V_EC required for a PNP transistor operating with an I_E of 50 mA and V_EB of 0.7V. If V_C = 0V, what does it indicate?

   Hint

   Ensure you consider the relationship between the voltages.

6. 6.

   If the collector current (I_C) of a PNP transistor is 15 mA and the β = 100, find the corresponding base current (I_B).

   Hint

   How do the currents relate in a transistor?
