Physics · Current Electricity
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): When electrons drift in a conductor, it does not mean that all free electrons in the conductor are moving in the exact same direction. Reason (R): The drift velocity is superposed over large random thermal velocities of electrons. Select the correct option:
- 1Both (A) and (R) are false.
- 2(A) is true but (R) is false.
- 3Both (A) and (R) are true but (R) is not the correct explanation of (A).
