How are emitter and collecter biased with respect to base in a transistor ?

Discuss about' the biasing of transistor.

For the transistor to act properly the emitter and collector junctions have to biased respectively as

How are pea seeds different from castor seeds with respect to endosperm?

In a common base circuit alpha = 0.99. Find the emitter and collector currents if the base current is 99 muA .

The 'emitter' 'base' and 'collector' regions of a transistor are doped respectively as
