We'll talk about three big ideas: electric potential difference (voltage), electric current, and electric field. Yes, they are all related, and I will show you how with some water and an LED.

Electric current is caused by moving electric charges. The effects of charge and electric fields can be investigated by looking at the forces they exert on conductors and insulators. Simple ...

Electromagnetism Description In this video, Jonny Nelson introduces an animated explanation of electromagnetism. Electromagnetism is due to the magnetic fields around electric currents.

A NASA-funded rocket mission is headed to space to measure the global electric circuit underlying the northern lights. For its second trip to space, the Aurora Current and Electrodynamics ...
