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.

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.

And this drop in potential energy, divided by the test charge's magnitude, gives us the electric potential energy difference per unit charge, also known as the electric potential. The electric ...

Last time, we learned that when there's a difference in electric potential between two points, the voltage gives charged particles, like electrons, the energy to move from one place to another.

Suppose there were two point charges, both positive but one is held in place. If I hold the other point charge a distance r away from the other charge and let go, what will happen?

Without a difference of potential, current cannot flow. Despite the availability of these products, many companies are still using improvised methods to create a ground-level EPZ, such as laying chain ...
