The accumulation of excess electric charge on an object.
Static electricity
States that charge can be transferred from one object to another but it cannot be created or destroyed.
Law of Conservation of charge
A region surrounding every electric charge in which a force of attraction or repulsion is exerted on other electric charges.
Electric Field
Material, such as copper wire, through which electrons can move easily.
Conductor
Material in which electrons and thermal energy are not able to move.
The transferring of electrical charge between objects by touching or rubbing.
Charging by contact
The rearranging of electrons on a neutral object caused by bringing a charged object close to it.
Charging by induction
A device, sometimes consisting of two leaves of metallic foil, used to detect electric charge.
Electroscope
The net movement of electric charges in a single direction, measured in amperes (A).
Electric current
Related to the force that causes electric charges to flow; measured in volts (V).
Voltage difference
A closed path that electric current follows.
Electric Circuit
Tendency for a material to oppose electron flow and to convert electrical energy into other forms of energy, such as thermal energy and light; measured in ohms.
Resistance
States that the current in a circuit equals the voltage difference divided by the resistance.
Ohm's Law
Circuit in which electric current has only one path to follow.
Series circuit
Circuit in which electric current has more than one path to follow.
Parallel circuit
Rate at which electrical energy is converted to another form of energy; expressed in watts (W).
Electrical power
The accumulation of excess electric charge on an object.
Static electricity
States that charge can be transferred from one object to another but it cannot be created or destroyed.
