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.
