This video tutorial discusses why excessive loading of a high-resistance voltage signal source causes substantial reduction in the intended voltage signal level. The voltage follower, a simple circuit based on an op amp, is presented as a circuit that replicates the source voltage signal with no loading effects to drive the load with the intended signal level.
