Vedclass · Answer

(D) diode acts as a unidirectional switch,allowing current to flow in one direction,which makes it suitable for rectification. Thus,statement $(A)$ is correct.$A$ triode can also be used as a rectifier by connecting its grid to the cathode,effectively making it act like a diode. However,in standard electronic circuit theory,a triode is primarily used for amplification. Statement $(B)$ is technically incorrect because a triode can be used as a rectifier.The amplification of a signal by a triode is achieved by operating it in the linear region of its $I-V$ characteristic curve,which ensures that the output signal is a faithful reproduction of the input signal without distortion. Thus,statement $(C)$ is correct.Since both $(A)$ and $(C)$ are correct,the correct option is $(D)$.
