Assertion (A): A large negative feedback is deliberately introduced in an amplifier to make its gain independent of variation is in parameters of active device and other components.

Reason (R): A large negative feedback results in a high value of return difference compared to unity which makes the feedback gain inversely proportional to feedback factor.
