Assertion (A): The current density ( \(\vec{{J}}\) ) at a point in a conducting wire is in the direction of electric field ( \(\vec{{E}}\) ) at that point.
Reason (R): A conducting wire obeys Ohm's law.
- 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.
Answer
(B) Both A and R are true but R is not the correct explanation of A.
