Term | Definition |
---|---|
Static Electricity | The accumulated electric charge on an object. |
Electric Force | The field force between tow charged objects. |
Law of Conservation of Charge | The principle that states that charge cannot be created or destroyed but only transferred between objects. |
Conductor | A material through which electric charge moves easily. |
Insulator | A material through which electric charge does not move easily. |
Current Electricity | Electricity involving moving electric charges. |
Electrical Circuit | The loop through which current electricity can flow. |
Resistance | The property of matter indicating the degree to which the material slows down the flow of charge carriers. |
Ohm's Law | The law that states that the current in a circuit is directly related to the voltage and inversely related to the resistance. |
Series Circuit | A circuit with only one path that electric current can take. |
Parallel Circuit | A circuit with multiple paths that electric current can take. |
Short Circuit | An unintended path for an electric current. |
Circuit breaker | An electrical safety device consisting of an automatic switch that opens when there is too much current in a circuit. |
Fuse | An electrical safety device that opens the circuit by melting when an overheated condition occurs due to excessive current. |
Electric power | The work per second done or produced by an electrical system. |
Resistor | An electrical device that slows down electric current by converting electrical energy into other forms, such as thermal energy. |
Voltage | The force that moves electric charge carriers through an electrical circuit; also called electric potential difference. |
Alternating Current | Electric current in which the charge carriers change direction periodically. |
Electric Field | A three-dimensional region around a charged object that will apply a force on other charged objects within that region. |
Grounding | The act of providing a path for electrical charge to move into the earth. |
Direct Current | Electric current in which electric charges move in only one direction. |
