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 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 ...

Learn how electric circuits work and how to measure current and potential difference with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

To start, remember that for a constant electric field the change in electric potential energy would be: WARNING: that is only for a constant electric field. I know you will be tempted later to use ...

Alessandro Volta (1745-1827) invents an electric battery, the first source of DC current. 1819 Hans Christian Oersted (1777-1851) finds that current in a wire can deflect a nearby magnetic needle.
