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 ...
The created surface holds a negative electrical charge, so when the positive ions in salt water move over the surface an electrical potential difference is created. That difference creates a voltage.
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.
