Question: In an inverting amplifier configuration, if the feedback resistor is 10kΩ and the input resistor is 1kΩ, what is the gain?

Options:

  1. -10
  2. -1
  3. 10
  4. 1

Correct Answer: -10

Solution: 

The gain of an inverting amplifier is given by -Rf/Rin, which in this case is -10kΩ/1kΩ = -10.

Questions & Step-by-Step Solutions

In an inverting amplifier configuration, if the feedback resistor is 10kΩ and the input resistor is 1kΩ, what is the gain?
  • Step 1: Identify the feedback resistor (Rf) and the input resistor (Rin). In this case, Rf = 10kΩ and Rin = 1kΩ.
  • Step 2: Use the formula for the gain of an inverting amplifier, which is Gain = -Rf / Rin.
  • Step 3: Substitute the values into the formula: Gain = -10kΩ / 1kΩ.
  • Step 4: Calculate the gain: -10kΩ divided by 1kΩ equals -10.
  • Step 5: Conclude that the gain of the inverting amplifier is -10.
  • Inverting Amplifier Gain Calculation – The gain of an inverting amplifier is calculated using the formula -Rf/Rin, where Rf is the feedback resistor and Rin is the input resistor.
