Unit: Electric charge, field, and potential
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.
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.
In these videos and articles you'll learn the difference between electric potential, electric potential energy, and voltage. You'll also learn how to calculate the electric potential at a point in space, electric potential energy between two charges, and voltage between two points in space.
About this unitElectric forces hold together the atoms and molecules in your eyes which allow you to read this sentence. Take a moment and learn about the force that holds our bodies together.
