Electricity
| Question | Answer |
|---|---|
| electron | a negatively charged particle that orbits the nucleus of an atom |
| electricity | flow of electrons |
| series circuit | circuit that has only one path for the electric current to follow |
| electric discharge | rapid movement of excess electron from one place to another, lightning is an example of this |
| conductor | Material, such as copper, silver,and iron, through which electrons can move easily |
| proton | a postively charged particle that is in the nucleus of an atom |
| voltage | measured in units of volts, measure of electric potential energy |
| electrical power | rate at which an appliance converts electrical energy to another form of energy |
| insulator | material, such as rubber, glass, through which electrons cannot move |
| static charge | buildup of electric charges in one place |
| Ohm's Law | relationship between voltage, current, and resistance in an electric circuit |
| resistance | measure of how difficult it is for electrons to flow through a material, unit is the ohm |
| nucleus | center of an atom, contains the protons and neutrons |
| neutron | is held tightly in the nucleus of an atom and does not have a charge |
| circuit | closed, unbroken path through which an electric current can flow |
| electric current | continuous flow of electrons through a conductor, measured in unit of amperes |
| parallel circuit | circuit that has more than one path for the electric current to follow |
