Logo Electronics Electricity, Components And Circuits Logo Electricity What is it? Logo The Atom Protons Electrons Neutrons Logo Electricity is Created When… One or more electrons are dislodged from an Atom. These free electrons become electricity. If an Atom is missing one of its electrons it becomes a positive Ion. If an Atom gains a extra electron it will become a negative Ion. Logo Electricity is created from.. - Heat - Friction - Nuclear reaction - Light - Chemical reaction - Magnetism Logo Key Terms - Conductor – allows electrons to flow through it - Insulator – blocks the flow of electrons - Current – a flow of electrons - Circuit – the path that electrical energy travels - Component – any electrical part that makes up a circuit - Terminal – the place where you connect a wire to a component. Logo Complete Circuit Logo Series VS Parallel Circuits Logo Series Circuit Complete Path Path is Broken Logo Parallel Circuit Logo Components Logo Key/Switch Opens or closes a circuit Logo Battery Stores energy and gradually lets it out as called for Logo Speaker Changes electrical energy to sound Logo Transistor Acts like a switch when hit with a small amount of electricity Logo Resistor Restricts the flow of electricity Logo Diode Allows electricity to flow in only one direction Logo Capacitor Stores electrons for a sudden discharge http://blog.makezine.com/archive/2009/02/make-presents-the-capacitor.html Logo Practice Quiz http://www.quia.com/quiz/856160.html
