WebJan 13, 2024 · What I never will understand is the following: Everybody starts the design of a BJT stage by generating a bias voltage VBE of app. 0.7 Volts. And, of course, he knows … WebAssertion (A): In active region of CE output characteristics of BJT, collector current is nearly constant. Reason (R): Base current in CE connection is very small. A. Both A and R are true and R is correct explanation of A B. Both A and R are true but R is not a correct explanation of A C. A is true but R is false D. hypochlorite sds sheet
