Inverting Amplifier

An inverting amplifier is a circuit that takes an electrical signal and increases its strength while reversing its phase. It works by using an operational amplifier (op-amp) and two resistors: one connects the input signal to the op-amp, and the other connects the op-amp's output back to its inverting input. When a voltage is applied to the input, the amplifier produces a larger voltage at its output that is opposite in direction (inverted) to the input. This setup is useful in electronics for signal processing tasks like amplification and filtering.
