What is operational amplifier? basics concepts
An operational amplifier is a DC-coupled high-gain electronic voltage amplifier amplifier that has high gain, differential input, high input resistance, and low output resistance.
Here are the basic electronics tutorial circuits for beginners. You can find here tutorials on operational amplifiers (opamp), transistor, MOSFETs, 555 timer IC, audio amplifiers and many more.
