Operational Amplifiers

Q1: The closed-loop voltage gain of an inverting amplifier equals:

A the ratio of the input resistance to the feedback resistance

B the open-loop voltage gain

C the feedback resistance divided by the input resistance

D the input resistance

ANS:C - the feedback resistance divided by the input resistance

Gain = -Rf/Ri for an inverting amplifier therefore C is the correct answer.
