Explore the key concepts of Chapter 18 on electric circuits in college physics. This video covers current, voltage, resistance, and circuit analysis techniques—perfect for students aiming to ...

The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an electric but also a magnetic current. It arises from the motion of electrons on an orbit around the nuclei of ...

Measurement triangle: this quantum metrology triangle shows the relations between the three electrical units volt, ohm and ampere and the involved fundamental constants. Researchers at PTB are ...

Incredibly, for the first time, scientists have unraveled the mechanisms at play when rubbing a surface creates an electrical current, something that was first recorded in 600 BCE yet not fully ...

A material cooled near absolute zero produced an electrical signal that physics said should not exist, revealing a new kind of quantum order.
