Q1:

In a bipolar transistor, the base collector junction has

A forward bias

B reverse bias

C zero bias

D zero or forward bias

ANS:B - reverse bias

In General bipolar transistors are used for the purpose of amplification. Transistor acts as amplifier only when it is operated in active region.

Then for a transistor to operate in active region the emitter base junction must be forward biased and the collector base junction must be reverse biased.
