How is a signal amplified in an op amplifier while the current does not flow (pass) through it?

Solving Op Amp circuits

Solving Op Amp circuits

Dan Bullard

This video uses the Jim Harris method of solving Op Amp circuits which requires virtually no math background, only a rough knowledge of Ohm's Law and Kirchoff's Law.
