Positive Charge= | Proton |
Negative Charge= | Electron |
Like charges | Repel |
Unlike charges | Attract |
The 3 parts of an atom | Proton, Neutron, & Electron |
Electrical Charge | The concentration of electricity |
Current | The discharge of electricity |
Insulator | Does not allow electricity to flow freely (rubber) |
Conductor | Allows current to flow freely (copper) |
Circuit | A complete or closed pathway through which charge flows |
Current | Rate at which electrical charges flow past a point in a circuit over a certain amount of time (A or I) |
Potential Difference | The charge in potential energy divided by the total energy |
Resistance | How much energy is changed to thermal or or light that electrical charges pass through |
Static Electricity | Build up of positive or negative charge caused by movement of electrons |
Chemical reaction | Causes energy in a battery |
Three ways to observe static electricity | Attraction, Repulsion, and Spark |
