Electric Potential Difference: Students learn to describe changes in the potential and kinetic energy of a point charge as it moves in an electrical field. Potential difference is introduced in terms ...

Nuclear fusion, which operates on the same principle that powers the sun, is expected to become a sustainable energy source ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Low-intensity electric fields can disrupt the division of cancer cells and slow the growth of brain tumors, suggest laboratory experiments and a small human trial, raising hopes that electric fields ...

Today I was talking about electric potential. My favorite analogy for electric potential energy is gravitational potential energy. But electric potential is something different. Electric potential ...

A drop in electric potential of just 0.55 V measured at altitudes of between 250–768 km in the Earth’s atmosphere above the North and South poles could be the first direct measurement of our planet’s ...

Shini explores electric current, voltaic cells, and how we get electric charge. Electric current works like a river... kinda... Instead of flowing based on elevation ...

An energy source inspired by the electric eel has been created by researchers in Switzerland and the US. The system mimics the thousands of thin “electrocyte” cells found in the animal, which it uses ...
