New research shows that these fields speed up water dissociation not by lowering energy costs, but by increasing molecular disorder once ions form. The reaction becomes entropy-driven—exactly the ...

Equipotential lines are curved lines on a map which mark out lines of identicalaltitude. The altitude pertains to electric potential or voltage. Equipotential lines are curved lines on a map which ...

The idea of electric field was introduced by Michael Faraday. The electrical field force acts between two charges, in the same way that the gravitational field force acts between two masses. The ...

For the first time, scientists have measured a long-sought global electric field in the Earth’s atmosphere. This field, called the ambipolar electric field, was predicted to exist decades ago but ...

In the home, the lab and the factory, electric fields control technologies such as Kindle displays, medical diagnostic tests and devices that purify cancer drugs. In an electric field, anything with ...
