Term | Definition |

Charging by Contact | involved touching a negatively charged object to a neutral object |
Charging by Induction | is a method used to charge an object without actually touching the object to any other charged object. |
Circuit | a roughly circular line, route, or movement that starts and finishes at the same place. |
Conductor | A material through which electric current can pass |
Electric Current | is a flow of electric charge |
Electrical Power | is the rate at which electrical energy is transferred by an electric circuit |
Insulator | a substance that does not readily allow the passage of heat or sound |
Law of Conservation of Charge | a principle stating that the total electric charge of an isolated system is fixed. |
Ohm's Law | states that the current through a conductor between two points is directly proportional to the potential difference across the two points. |
Parallel Circuit | is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit. |
Resistance | the refusal to accept or comply with something; the attempt to prevent something by action or argument. |
Series Circuit | is a closed circuit in which the current follows one path |
Static Electricity | a stationary electric charge, typically produced by friction, that causes sparks or crackling or the attraction of dust or hair. |
Voltage Difference | the difference in electric potential energy between two points per unit electric charge |
