Question 3
A transistor has a common emitter gain (β) of 100. If the base current is 20µA, calculate the:
- Collector current;
- Emitter current;
- Common base current gain (α);
- Common collector current gain (γ).
Observation
The Chief Examiner reported that majority of the candidates could not recall the relationship between the various d.c. current flows in a bipolar junction transistor.
The expected responses were:
