Question

Write clearly, why in the case of a transistor (i) the base is thin and lightly doped

Solution

In a transistor, the base is thin and lightly doped so that it contains smaller number of majority carriers. This reduces the recombination rate of free electrons and holes in the base region when the majority carriers go from the emitter to the collector.
