Summary |
Introducing fundamental concepts of static electricity through instruction, demonstrations and hands-on activities. Electric field, electric potential difference, and capacitance are the three main topics. |
| |
Objectives |
- Students understand that charging is the separation, not the creation, of electric charges.
- Students will know how an electroscope works and how to construct a simple electroscope.
- Students will understand how electric charges are distributed on charged conductors and how electric discharging related to a conductor’s shape (actually curvature).
- Students will know some common applications of utilizing and avoiding static electricity.
