Q1:

If for a silicon n-p-n transistor, the base to emitter voltage (VBE) is 0.7 V and the collector to base voltage VCB is 0.2 Volt, then the transistor is operating in the

A normal active mode

B saturation mode

C inverse active mode

D cut off mode

ANS:A - normal active mode

Transistor will operate in active mode because VBE = 0.7 volt, (Base emitter junction is forward biased) VCB = - VBC = - 0.2 V (Base to collector junction is reverse biased).
