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.

Parts of the video:
0:00 Introduction
0:36 What's the point of a voltage follower?
0:54 High- versus low-impedance outputs
3:47 Simulating a high-impedance output
4:38 Setting up the op-amp voltage follower
6:01 Trade-offs
8:21 The toast will never pop up
