| Electric charge | A property that allows one object to exert an electric force on another object without touching it |
| Electric field | An area surrounding a charged object, within which the object can exert an electric force on another object without touching it |
| Static charge | The buildup of electric charge in an object caused by the uneven distribution of charged particles |
| Induction | The buildup of a static charge in an object when the object is close to, but not touching, a charged object |
| Electric potential | The amount of potential energy per unit charge that a static charge or electric current has |
| Volt | The unit of measurement for electric potential, which is equal to one joule per coulomb |
| Conductor | A material that transfers energy easily |
| Insulator | A material that does not transfer electric charge easily |
| Resistance | The property of a material that determines how easily a charge can move through it; measured in ohms |
| Ohm | The unit of measurement for electrical resistance |
| Grounding | The creation of a harmless, low-resistance path - a ground - for electricity to follow |
| Electric current | A continuous flow of electric charge, which is measured in amperes |
| Ampere | The unit of measurement of electric current, which is equal to one coulomb per second. |
| Ohm's Law | The mathematical relationship amoung current, voltage, and resistance, expressed in the formula I=V/R |
| Electric cell | A device that produces electric current using the chemical or physical properties of different materials |
