Logo Electronics Electricity, Components And Circuits

Logo Electricity What is it?

Logo The Atom Electrons Protons 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 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
