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 $\displaystyle \beta$ 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.
Official answer
(4)
Statement I is false but Statement II is true
