Materials and Components
Assertion (A): In a conductor, current density remains constant in time as long as E is constant. Reason (R): In a conductor, J = σE.
Both A and R are true and R is correct explanation of A
Both A and R are true but R is not correct explanation of A
A is true but R is false
A is false but R is true
Correct Answer:
Both A and R are true and R is correct explanation of A
Explanation:
In conductors constant E means constant current because conductivity is constant.
