Question 1.
What is the definition of an n-p-n transistor?
Show hintHide hint
Think about the arrangement of n and p-type materials.
Question 2.
What direction does current flow in a p-n-p transistor?
Show hintHide hint
Remember the arrangement of p and n materials.
3Question 3.
What is the primary condition for an n-p-n transistor to operate in the active region?
- Base-collector junction must be forward biased
- Base-emitter junction must be forward biased
- Both junctions must be in reverse bias
Show hintHide hint
Think about the necessary voltage conditions for functioning.
4Question 4.
In a p-n-p transistor, current flows from the
- Base to Emitter
- Emitter to Base
- Collector to Emitter
Show hintHide hint
Reverse the flow compared to an n-p-n transistor.
Question 5.
Design a circuit using a p-n-p transistor. Describe the component values you would use to ensure the transistor remains in its active region.
Show hintHide hint
Sketch the circuit and label each part, focusing on biasing.
Question 6.
If a circuit shows an n-p-n transistor with a base resistor of 1kΩ and a collector resistor of 4.7kΩ, calculate the collector current under given conditions where the base current is 8mA.
Show hintHide hint
Estimate β and consider how it relates to the provided currents.
