NEET Physics Ohm's Law Assertion Reason Question
Assertion (A): A diode does not obey Ohm's Law. | Reason (R): The plot of current versus voltage for a diode is non-linear.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The NCERT text states that a diode does not obey Ohm's Law because the plot of current versus voltage for a diode is non-linear, confirming the reason explains the assertion.
