Answer to Question #29133 in Electric Circuits for smrutidhara
what is an opamp?
An operational amplifier (op-amp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. An op-amp produces an output voltage that is typically hundreds of thousands of times larger than the voltage difference between its input terminals. Op-amps are among the most widely used electronic devices today, being used in a vast array of consumer, industrial, and scientific devices.
