Ohms Law In a conductor where a electric field is established electrons are free to move. The electrons move from a place where their electrical potential is high to a place where they have less electrical potential, the electrons are said to flow at this time. This is analogous to water flowing through a pipe or hose. The water will flow from a place of higher potential energy to a place of lower potential energy. The flow of electrons is called the electric current . Current is represented by , I , and has units of amps . Current is the amount of electric charge which flows in a second. Other terms to become familiar with are volts and voltage , which are terms associated with electric potential difference and represented by V the units are called volts and uses the term v. A battery is a voltage source, when a wire is connected across the two terminals of the battery a current is established and flows in one direction. The common convention is to say that current flows from the positive terminal to the negative terminal. How much current can flow in a wire is determined by the resistance the electrons encounter in that wire. Resistance which is represented
