An instrument always extracts some energy from the measured medium. Thus the measured quantity is always disturbed by the act of measurement, which makes a perfect measurement theoretically impossible and it is due to
Directions: Each of the next items consists of two statements, one labeled as the `Assertion (A)' and the other as 'Reason (R)' You are to examine these two statements carefully and select the answers to these items using the codes given below :Assertion (A) : For time varying field the relation E̅ = - ∇̅ V is inadequate. Reason (R): Faraday's law states that for time-varying field ∇̅ × E̅ = 0.
