Question 526Electricity & Electronics - Assistant Engineer

The correct answer is D) high input impedance, high gain and low output impedance. Operational amplifiers (op-amps) are characterized by high input impedance, high gain, and low output impedance. This configuration allows op-amps to effectively amplify and condition analog signals with minimal loading effects on the input circuit. The high input impedance ensures that the op-amp does not draw significant current from the input, the high gain provides substantial amplification, and the low output impedance allows the op-amp to drive various loads without significant voltage drops. The other options are incorrect because they do not accurately describe the typical characteristics of op-amps. Option A describes the characteristics of a voltage follower, while options B and C do not accurately reflect the high gain and low output impedance properties of op-amps.
