Question

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

(1) The base region must be very thin and lightly doped. 

(2) Base, emitter and collector regions should have same doping concentrations. 

(3) Base, emitter and collector regions should have same size. 

(4) Both emitter junction as well as the collector junction are forward biased.

Answer 1

Correct answer is (1) The base region must be very thin and lightly doped.

Base region is very thin and lightly doped.
