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) What is Electric Charge?
2) The Earth's electric charge, and Lightning
3) Coulomb's Law
4) Electric Field
5) Electric Potential
6) Electric Potential due to a Point Charge
7) Relation between electric field and electric potential
8) Solved Problems
