The voltage gain formula for a closed-loop op amp is ________. A) R_f / R₁ + 1 B) R_f / R₁ C) R_f x R₁ D) R_f x R₁ + 1

Question

Quizplus · Accepted Answer

The correct formula for the voltage gain of a closed-loop operational amplifier (op amp) is given by the expression that represents the gain as a function of feedback and other parameters, which is typically in the form of a ratio involving feedback resistance and other factors. Option A is the correct choice as it resembles the standard format for such a formula, despite the use of placeholder symbols.
