Physics Special - Potential Difference in a Nutshell


Let's revise this with the Al-Farabian way - using easy illustration:

1. Similar charges repel each other.

2. They are brought closer to each other, creating repulsive force.

3. Energy is needed to bring these charges closer to each other.

4. The work done (to bring them closer) is called potential difference.

5. The whole thing happens in the electric field.
