The answer is 1.5 kohms because the formula is gain is
1 + R2/R1 where R2 is the feedback resistor and R1 is the input resistor. #EngineeringQuizzes #EngineeringProfessor #NoireSTEMinist #MySTEMIsForTheStreets

2610 followers · 2488 posts · Server blacktwitter.io@vk2bea The input resistor is the one tied to grounds from the inverting input. There could also be one a the voltage soure to the non-inverting input but it won't impact the gain. This is not a difference amplifier, I'm trying to keep things simple. #EngineeringQuizzes ππΎ

An inverting amplifier has an input resistance of 2kΞ©. The ampliifer should have a gain of -1/2, what is the value of the feedback resistor?

A 10V source sees two resistors in series with an equivalent resistance of 20kΞ©. If one resistor must drop 3V, what are the two resistors?
