Description

The idea of a "virtual ground" makes some simplifying assumptions, giving us an elegant and simple way to look at op-amp circuits.

Electrical engineering

Learn about electricity, circuit theory, and introductory electronics. We also have sections that let you get down and dirty with household items, from building your own robot to videos where we disassemble household items to see what's inside.

Operational amplifier

The operational amplifier, or "op-amp", is a common type of amplifier used everywhere in analog electronics. The op-amp has very high gain and differential inputs.

Topic: Science

Learn about all the sciences, from physics, chemistry and biology, to cosmology and astronomy, acros…
