Vedclass · Answer

(C) In a transistor,the base is made very thin and lightly doped to ensure that most of the charge carriers injected from the emitter pass through to the collector.If the base were thick,more charge carriers would recombine in the base region,leading to a large base current $(I_b)$ and a significantly reduced collector current $(I_c)$.Since $I_e = I_b + I_c$,a thin base minimizes $I_b$,allowing for high current gain.The reason provided,'$A$ thin base makes the transistor stable',is incorrect because the primary purpose of a thin base is to ensure efficient charge carrier transport and high current gain,not stability.Therefore,the Assertion is correct,but the Reason is incorrect.

Assertion: In a transistor,the base is made thin.
Reason: $A$ thin base makes the transistor stable.
