Question
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A : A diode under reverse- biased condition provides very small current which is nearly independent of voltage until a critical limit at which the current increases drastically.
Reason R : Below the critical voltage limit, only majority charge carriers flow which increases drastically above critical voltage.
Choose the correct answer from the options given below.
Options
A.Both $\mathbf{A}$ and $\mathbf{R}$ are true and $\mathbf{R}$ is the correct explanation of $\mathbf{A}$.
B.Both $\mathbf{A}$ and $\mathbf{R}$ are true but $\mathbf{R}$ is NOT the correct explanation of $\mathbf{A}$.
C.$\mathbf{A}$ is true but $\mathbf{R}$ is false
D.$\mathbf{A}$ is false but $\mathbf{R}$ is true
Solution
Sol. [Key Concept: A is true; R is false — reverse saturation current is carried by minority (not majority) carriers.]
