Term
 ELECTRICAL CHARGE
Definition
 A condition that results from an imbalance between the number of protons and the number of electrons in a substance
Term
 INDUCTION
Definition
 Creating a charge in an object WITHOUT direct contact
Term
 ATTRACTION
Definition
 Happens between two oppositely charged objects

Term
 ELECTRON
Definition
 A subatomic particle with negative (elementary) electric charge that is found within an atom (Symbols: e, e-, or I-)
Term
 CONDUCTION
Definition
 The movement of electrically charged particles through a transmission medium.
Term
 SOLENOID
Definition
 A coil of wire around an iron core that produces a magnetic field when carrying an electric current
Term
 GROUNDING
Definition
 Allowing charges to move freely along a connection between a conductor and the ground.
Term
 PARTICLES
Definition
 A particle is a small localized object to which can be ascribed several physical properties such as volume or mass.
Term
 POWER
Definition
 The rate at which electric energy is transferred by an electric circuit. Ex: Measured in Watts (Joules/Second).
Term
 VOLTAGE
Definition
 The difference in electrical charge between two points in a circuit is the voltage of the circuit (expressed in volts).
Term
 RESISTOR
Definition
 A device (usually electrical) that resists the flow of electrical current.
Term
 PROTON
Definition
 A subatomic particle that has a positive charge and that is found in the nucleus of an atom. (Symbols: p, p+ or I)
Term
 NEUTRON
Definition
 An elementary particle with no net electric charge and mass slightly larger than that of a proton, that is found within an atom. (Symbols: n or n0)
Term
 INSULATOR
Definition
 A material that does not respond to an electric field and completely resists the flow of electric charge.
