MCQ

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 :

✓
Statement $I$ is false but Statement $II$ is true
B
Both Statement $I$ and Statement $II$ are true
C
Both Statement $I$ and Statement $II$ are false
D
Statement $I$ is true but Statement $II$ is false

✓

Answer

Correct option: A.

Statement $I$ is false but Statement $II$ is true

a
Back to back diode will not the make a transistor

$\beta=\frac{ i _{c}}{ i _{ b }}$
