In these videos and articles you'll learn what an electric field is and how to calculate the value of the electric field for a point charge and an infinite sheet.
Charge_and_electric_force_Coulomb_s_law_
In these videos and articles the definition of electric charge will be given as well as a discussion of the law of conservation of charge. You'll learn how Coulomb's law relates the electric force to charge and separation distance. The difference between an electrically conducting vs. electrically insulating material will also be discussed.
