LECTURE NOTES

- Potential Energy and Potential
- Capacitors

KEY ITEMS:

• The concept of potential is a difficult one for the students. It is
important to clarify that the electric field and electric potential of
source charges exist in space and that they are independent of
the presence of a test charge.

• The following are terms that are often misinterpreted.:
- electric potential and electric potential energy
- electric potential and potential difference.
