Terms in this set (20)
A material that conducts heat and electricity WELL.
A subatomic particle that has a negative charge.
Matter that has equal amounts of positive and negative charges.
The flow of electric charges (electrons).
A property of matter that tells whether something has a positive or negative charge.
The space around a charged object in which another charged object experiences an electric force.
A force that one charge exerts on another. When the charges are the same sign, they repel; when the charges are opposite, they attract.
A material that does NOT conduct heat well.
Negatively Charged (-)
Matter that has more negative charges than positive charges.
Positively Charged (+)
Matter that has more positive charges than negative charges.
A buildup of charges on an object.
The rapid movement of excess charge (electrons) from one place to another.
The path that an electric current flows.
A circuit in which all parts are connected end to end to provide a SINGLE path of current.
A circuit in which the current is divided into TWO or MORE paths.
Direct Current (DC)
A flow of electrons in one direction through an electric circuit. Ex. Batteries
Alternating Current (AC)
a flow of electric charge that regularly reverses its direction. Ex. anything you plug in to the wall
The energy of electric charges or electricity.
An incomplete electrical circuit in which no current flows.
