Ch.6 Sec.1 Flashcards
Static electricity
An imbalance of electric charges within or on the surface of a material
And uneven amount of electric charges in or on the surface of a material
Ex. Rubbing your shoes on carpet and touching someone
Law of conservation of charge
The principle that electric charge can neither be created nor destroyed
Electric change can’t be destroyed or created
Ex. Brushing your hair
Electric field
A region around a charged particle or object within which of course can be exerted on other charged particles or objects
An area around the charge particle or object in which of course can be put on another charge particle or object
Ex. Cannot be seen but can be observed
Conductor
Materials through which excess electrons can move more easily
Electrons move easily
Ex. Aluminum
Insulator
Materials to which excess electrons cannot move easily
Electrons don’t move easily
Ex. Glass
Charge by contact
Process of transferring to charge by touching or contact
Charge transferred by touch or contact
Ex. Electric shock
Charge by induction
The rearrangement of electrons on a neutral object caused by a nearby charged object
Rearrangement of electrons caused by a nearby charged object
Ex. Electrified railways
Electroscope
A device that detects electric charges
Detector of electric charges
Ex. Arrow
Coulombs
The SI unit of electric charge, equal the quantity of electricity conveyed in one second by current of one ampere
SI unit of electric charge = quantity of electricity conveyed in one sec
Ex. C
Grounding an object
Connecting an object to earth with a conductor
Nonconducted object on earth
Ex. Negative and positive charts
Electric current
A flow of electric charge. Often carried by moving electrons in a wire
Electric charge flowing
Ex. Lights
