A review of electric charge, electric field surrounding the charge, and relating it to gravitational field... Electric field is a vector quantity, with magnitude and directions. Discussion of how the magnitude is affected by the charge size... We reviewed gravitational potential energy, and related it to electrical potential energy. We determined the work done in moving a single charge against an electrical field. Differentiation between electric potential energy and electric potential was discussed. The unit of the volt was introduced, along with voltage. Electric potential was shown as the total electrical potential energy/unit of charge. A short video was shared showing how a capacitor works.
