Question 1.
What type of materials make up a p-n-p transistor?
Show hintHide hint
Think about the material types designated in their names.
Question 2.
What does β represent in a transistor?
Show hintHide hint
It's a measure of how much current is amplified.
3Question 3.
What is the primary difference between a p-n-p and an n-p-n transistor?
- p-n-p has a negative base-emitter voltage
- n-p-n has a p-type emitter
- p-n-p has a p-type emitter
Show hintHide hint
Think about the definitions of 'p' and 'n'.
4Question 4.
True or False: The gain of a transistor is denoted by gamma (γ).
- True
- False
Show hintHide hint
Recall the Greek letters associated with transistor characteristics.
Question 5.
If given a p-n-p transistor with a gain (β) of 120 and a base current (I_B) of 10 µA, what would be the collector current (I_C)?
Show hintHide hint
Use the gain formula to determine the collector current.
Question 6.
In a circuit using both p-n-p and n-p-n transistors, how would you determine which one to use for a particular amplification requirement?
Show hintHide hint
Understand the conditions under which each operates best.
