Coulombs (unit of charge) fundamental unit of charge. Electric fields are created by . electric charges. . Any object with a charge has an electric field around it. Opposite charges attract each other; like charges repel. An electric field is a region in which a charge experiences a force. . By: Raiden Foris. The attractive or repulsive interaction between any two charged objects is an . electric force. . . video. What is electric force?. Coulomb’s law. The symbol . k. is a proportionality constant known as the Coulomb's law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 10^9 N • m^2 / C^2. . What is . electric . potential?. How does it relate to . potential energy. ?. How . does it relate to . electric field. ?. Some simple applications. Electric potential. What does it mean when it says “1.5 Volts” on the battery?. 1. When the balloon is rubbed on the sweater, what might happen?. A. . Some positive charges in the sweater will move onto the balloon. B. Some negative charges in the sweater will move onto the balloon. © 2014 Pearson Education, Inc.. Contents of Chapter 16.
