Batteries‚ Resistance and Current “Battery-Resistor”: Check “show battery” and “show cores”‚ watch what happens‚ adjust some variables 1. Why do electrons (blue dots) move? Draw a diagram of the battery‚ label the flow of electrons. The flow of current (+) is opposite; draw this and note if toward or away from + terminal of the battery. The blue dots indicating the electrons move because there is a voltage across the battery in which the electrons flow away from the positive terminal

Commercial Cells Galvanic Cell A Galvanic cell is also known as a Voltaic cell. It was named after Luigi Galvani and Alessandro Volta. A galvanic cell is capable of producing an electric current from a redox reaction that occurs within it and consists of two half cells. Each half cell consists of an electrode and electrolyte and a salt bridge. In a galvanic cell one metal can undergo reduction and the other oxidation. A typical galvanic cell is based on the spontaneous redox reaction: Net Ionic
