Physical Science Electricity terms - Ch. 20 Prentice Hall Science Explorer

QuestionAnswer
electric force the attraction or repulsion between electric charges.
electric field is a region around a charged object where the object's electric force is exerted on other charged objects
static electricity a buildup of charges on an object.
conservation of charge the law that states that charges are neither created nor destroyed but only transferred from one material to another.
friction The force that one surface exerts on another when two surfaces rub against each other
conduction a method of charging an object by allowing electrons to flow by direct contact from one object to another object
induction a method of charging an object by means of the electric field of another object
static discharge the loss of static electricity as electric charges transfer from one object to another
electric circuit a complete, unbroken path through which electric charges can flow
conductor a material through which charges can easily flow
insulator a material through which charges cannot easily flow
voltage the difference in electrical potential energy between two places in a circuit
voltage source a device that creates an electrical potential energy difference in an electrical circuit
resistance the measurement of how difficult it is for charges to flow through a material
chemical energy a form of potential energy that is stored in chemical bonds between atoms
chemical reaction the process in which substances undergo chemical changes that result in the formation of a new substance
electrochemical cell a device that transforms chemical energy into electrical energy
electrode a metal part of an electrochemical cell, which gains or loses electrons
electrolyte a liquid or paste that conducts electric current
terminal a convenient attachment point used to connect a cell or a battery to a circuit
battery a combination of two or more electrochemical cells in a series
wet cell an electrochemical cell in which the electrolyte is a liquid
dry cell an electrochemical cell in which the electrolyte is a paste
Ohm's law the law that states that resistance is equal to voltage divided by current
series circuit an electrical circuit with a single path
ammeter a device used to measure current in a circuit
parallel circuit an electric circuit with multiple paths
voltmeter a device used to measure voltage, or electrical potential energy difference.
power the rate at which one form of energy is transformed into another
short circuit a connection that allows current to take an unintended path
grounded allowing charges to flow directly from the circuit into Earth in event of a short circuit
third prong the round prong of a plug that connects any metal pieces in an appliance to the safety grounding wire of a building
fuse a safety device with a thin metal strip that will melt if too much current passe through a circuit
circuit breaker a reusable safety switch that breaks the circuit when the current becomes too high
