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.
Solution
<b>S-1 :</b><br><br>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.<br><br><b>S-2 :</b><br><br>Statement-2 is true, as we know that, amplification factor ($\beta$) is the ratio of collector current to base current.<br><br>$\beta = {{{I_C}} \over {{I_B}}}$
