This subject is difficult usually. This course starts with an image and animation to show electric charges, and goes on to the concept of electric field strength, and electric potential. Just like gravitation, wherever there is a kind of force, there will be energy, so electric potential energy is necessary to understand.
Following topics are covered:
1. Electric charge, units
2. Coulomb’s Law
3. Electric field
4. Lines of electric force
5. Electric Potential energy
6. Electric potential
7. Relation between electric field and potential
8. Electric dipole
9. Electric field due to dipole
10. Torque on a dipole kept in an electric field.
11. Conductors, Insulators and Semi-conductors.
12. Electric field inside a conductor.
Solved problems and test questions are given at the end.
