| static electricity | the accumulation of excess electric charge on an object |
| conductor | a material in which electrons are able to move easily . They move easily because the electrons are loose or far apart. |
| insulator | material in which elecrons are not able to move easily (they are packed in tightly) |
| circuit | the closed path that electric current follows |
| resistance | the tendency for a material to oppose the flow of electrons, changing electricityenergy into thermalenergy and light |
| equation for Ohm's Law | current equals voltage difference divided by resistance |
| series circuit | a circuit in which electrical current has only one path to follow |
| parallel circuit | a circuit where electrical current has more than one path to follow |
| electrical current | the net movement of electric charges in a single direction, measured in amperes |
| current | the flow rate of electrons through wire in the circuit and is measured in amperes |
| voltage | is the measure of the electromotive force or pressure that causes electrons to move. It is measured in volts. |
| opposites | attract |
| same | repel |
