Notes

battery: a device used for generating electricity through a electrochemical reaction ; a battery unit is made from one or more cells. Circuit: A complete path for an electric current Closed Circuit: where the current flows from the battery through an electrical device providing power, and returning back to the battery Conductor: anything an electrical current can pass through easily. Electricity: a type of energy in which small particles (called electrons) move through a device. Electron: part of an atom; a negatively charged particle that is found outside of the nucleus of the atom Energy: the capacity for doing work ; may be electrical mechanical chemical thermal or nuclear. Friction: resistance between two surfaces moving against each other. Insulator: materials that electricity has a hard time flowing through eg: plastic coating on wires leather wood etc Kilowatts: a unit of electricity power equal to one thousand watts. Manufactured: man made Natural: found in nature Negative charge: having more electrons than protons Neutron: an uncharged particle in the nucleus of an atom Nucleus: central part of an atom made of protons and neutrons Open circuit: an incomplete path electricity can not cross the break in the circuit
