FPC - Chapter 20 Electricity
electric charge - ANS-this is a property that allows particles with like charges to repel and
opposite charges to attract

electric force - ANS-this is the force of attraction or repulsion between electrically charged
objects

electric field - ANS-the effect an electric charge has on other charges in the space around it

static electricity - ANS-the study of behavior of electric charges including how charges are
transferred between objects

law of conservation of charge - ANS-the total charge in an isolated system is constant

induction - ANS-a transfer of charge without touching

electric current - ANS-the continuous flow of electricity

direct current - ANS-electric charge that flows in only one direction

alternating current - ANS-electric charge that regularly reverses it direction

electrical conductor - ANS-a material through which electric charge can flow easily

electrical insulator - ANS-a material through which electric charge cannot flow easily

resistance - ANS-opposition to the flow of charges in a material

superconductor - ANS-a material that has almost zero resistance when it is cooled to low
temperatures

potential difference - ANS-the difference in electrical potential between two places in an electric
field

voltage - ANS-another name for potential difference

battery - ANS-a device that converts chemical energy to electrical energy

Ohm's Law - ANS-the relationship which states: the resistance equals the voltage divided by the
current
