PPT-Today: Chapter 23: Electric Current

Still waiting for scantron results Electric Current Is the flow of electric charge ie charged particles usually electrons between regions of different electric potential When there is no potential difference there is no charge flow no current. Current and Resistance. TexPoint fonts used in EMF. . Read the TexPoint manual before you delete this box.: . A. A. A. A. A. A. A. Introduction to chapter 25. In this chapter we will start the study of . The next few slides are not on your note. They are just interesting. Electric Fish, Eels, and . Rays. For humans, we know that water and electricity . are . not good to mix. For some animals, this safety concern about electricity is not a problem. In fact, they survive because they can use electricity in the . Electric Potential. QUIZ. Define electric force. What is charge measured in?. If two charges are opposite, what happens to those charges?. 4. The force between two charges can be calculated using the following equation . Electric current. . is the rate of electron flow past a specific point in the circuit (how . fast . electrons pass . through a . point in the wire).. The symbol for electric current is . I. ..
