| 1. | Resistor Rc is the collector load resistor for the collector current.
|
| 2. | This causes a base current and much larger collector current to flow.
|
| 3. | It shows the collector current in the transistor " I"
|
| 4. | The collector current has two components : minority carriers and majority carriers.
|
| 5. | Collector current is approximately ? ( common-emitter current gain ) times the base current.
|
| 6. | The physical explanation for collector current is the concentration of minority carriers in the base region.
|
| 7. | That is, the collector current is approximately \ beta _ F times the base current.
|
| 8. | The maximum collector current I C ( max ) of the pair is that of Q 2.
|
| 9. | Additional matched transistors can be connected to the same base and will supply the same collector current.
|
| 10. | Under this condition all three transistors have nearly equal collector currents and therefore approximately equal base currents.
