For transistor action, which of the following statements are correct ?

1.	For transistor action, which of the following statements are correct ?A. (a) Base , emitter and collector regions should have similar size and doping concentrationsB. (b) The base region must be very thin and lightly dopedC. ( c) The emitter junction is forward biased and collector junction is reverse biasedD. (d) Both the emitter junction as well as the collector junction are forward biased
Answer» Correct Answer - B::C In a transistor , base must be very thin and lightly doped so that all of the charge carries are not combined in base and majority of them passes the reverse bias layer to collector side.
