Скачать или смотреть Operational Amplifiers (Op Amps) and its Characteristics, Physics Lecture | Sabaq.pk

In this video, we will study Operational Amplifiers, widely used in analog electronic circuits for amplification and performing mathematical operations such as addition, subtraction, integration, and differentiation. Found in nearly every electronic chip and device, operational amplifiers are essential electronic components built as an integrated circuit.

We begin by discussing the structure of operational amplifier, which is typically made from silicon and powered by a dual power supply to allow both positive and negative output swings. We also explain the symbol of operational amplifier, which includes a non-inverting input, an inverting input, and a single output terminal.

The role of DC Voltage at the inputs and how it influences the output voltage is examined in detail. The video also covers key characteristics of operational amplifiers, such as high input resistance (often in mega ohms), low output resistance, and open loop gain — all of which allow precise amplification of small voltage differences.
