Voltage Follower - Operational Amplifier | Basic Circuits | Electronics Tutorials

Video Description

Operational amplifiers, or op-amps, have a variety of popular configurations but one of the most often used is as a voltage follower. In this video, Josh goes over the concept behind a voltage follower, where and why you'd need it, and does a practical example showing how it affects the output voltage of a high-impedance source.
