Question

the use of negative feedback
select one:
a. eliminates linear operations
b. increases the power dissipation
c. reduces the voltage gain
d. makes the op amp oscillate

Explanation:

Negative feedback in amplifiers feeds a portion of the output signal back in phase opposition to the input. This intentionally lowers the overall voltage gain, but improves stability, linearity, and other performance characteristics. Option a is incorrect because negative feedback enhances linear operations, option b is incorrect as it does not increase power dissipation, and option d is incorrect because positive feedback (not negative) causes oscillation.

Answer:

c. reduces the voltage gain
