Op-Amp Tutorial: Non-Inverting Amplifier with Waveform Analysis

In this video, we demonstrate the step-by-step construction and simulation of a Non-Inverting Operational Amplifier (Op-Amp) circuit using a mobile circuit simulation tool.
We begin by selecting the required components from the simulator library, including an operational amplifier, resistors, an AC voltage source, and ground. Then, we carefully wire the circuit in a non-inverting configuration, set resistor values to control the gain, and run the simulation.
Finally, we analyze the input and output waveforms using an oscilloscope to observe how the signal is amplified without phase inversion, which is a key property of a non-inverting amplifier.
This video is ideal for electronics students, beginners, and anyone learning Op-Amp fundamentals.
