Given below are two statements :


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.

  1. Statement I is false but Statement II is true.

  2. Both Statement I and Statement II are true.

  3. Statement $\mathrm{I}$ is true but Statement II is false.

  4. Both Statement I and Statement II are false.

Correct Option: 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.


Statement-2 is true, as $\beta=\frac{I_{C}}{I_{B}}$
