| Electric Charge | fundamental property of matter; comes in two forms |
| Voltage | is the difference in the electrical potential between two points in a circuit |
| Water tower and pump | good analogy for a battery |
| safety device that reacts to specific levels of current | circuit breaker |
| safety measure that reacts to certain levels of current | ground fault circuit interrupter |
| Current | flowing charges |
| Conductors | electrical current passes easily through |
| Where do almost all of the electrons flowing in a battery circuit come from? | atoms in the wire conductor |
| Good conductors of electricity | metals |
| Electrical Resistance | ability of an object to resist current |
| Unit of measurement for resistance | Ohm |
| Ohm's Law | mathematical relationship between current, voltage and resistance |
| Resistors | Components on a circuit board used to control current |
| Neutral objects | equal amount of positive and negative charge |
| Voltage | measure of potential energy of an electric charge |
| Current | flow of electric charges in a circuit |
| Insulator | material through which charges do not flow |
| Conductivity | property of material that allows charge to flow |
| Battery | device that uses chemical reactions to separate positive and negative charges |
| Static Electricity | the buildup of charges on an object caused by triction |
| Parallel Circuit | is an electric circuit with several paths for the current to take |
