a. Electric potential is a scalar quantity and electric field is a vector quantity. b. Electrical potential energy is a form of work.
Work Step by Step
a. Electric potential is a scalar, measured in volts, and is the electric potential energy per unit charge at a particular location in space. Electric field is a vector, measured in N/C, and is the electric force per unit charge at a particular location in space. b. Electric potential energy is energy stored in a configuration of charges. It is the work performed in moving a charge from a starting location (defined to be zero potential energy) to a final location.
