4C: Ouch! have you ever heard of people being struck by lightning? Have you ever seen a defibrillator used to shock a patient back from the jaws of death? These amazing phenomena are possible due to the action of electric charges. Like masses, electric charges can have an associated force and a potential energy within a field. In these tutorials, you will discover how electric charges interact with one another and will arrive at an understanding of the concepts of electric force, fields, and potential.
