Inverting Amplifier with Variable Gain

Overview

This experiment demonstrates the design of an inverting amplifier with adjustable gain using operational amplifiers.

Components Required

• Op-Amp
• Resistors
• Variable resistor (for gain adjustment)
• Power supply
• Breadboard and wires

Procedure

1. Connect the op-amp in an inverting amplifier configuration with a variable resistor to adjust gain.

2. Vary the resistance and observe the change in output signal amplitude.

Expected Result

The output signal will be an inverted version of the input, with the amplitude varying based on the adjusted gain.
