Question:
Given below are two statements :
Statement I : PN junction diodes can be used to function as transistor, simply by connecting two diodes, back to back, which acts as the base terminal.
Statement II : In the study of transistor, the amplification factor $\beta$ indicates ratio of the collector current to the base
current. In the light of the above statements, choose the correct answer from the options given below.
Correct Option: 1
Solution:
(1)
$S-1$
Statement 1 is false because in case of two discrete back to back connected diodes, there are four doped regions instead of three and there is nothing that resembles a thin base region between an emitter and a collector.
$\mathbf{S}-2$
Statement-2 is true, as $\beta=\frac{I_{C}}{I_{B}}$
