ANSWERS 100% CORRECT
Electricity - ANSWER-The energy of the flow of electrons in a conductor
Conductor - ANSWER-A material that has little resistance and permits electrons to
move through it easily
Atom - ANSWER-The smallest particle that has a positive electrical charge of one unit
Proton - ANSWER-A subatomic particle that has a charge of one unit
Neutron - ANSWER-A subatomic particle that has no electrical charge
Electron - ANSWER-A subatomic particle that has a negative electrical charge of one
unit
Nucleus - ANSWER-Dense center of an atom, consisting of protons and neutrons
Current - ANSWER-the flow of electrons through a conductor
Direct current - ANSWER-Current that flows in one direction only
alternating current - ANSWER-Current that reverses it's direction of flow at regular
intervals
Open circuit - ANSWER-A circuit having a incomplete path
Closed circuit - ANSWER-A circuit having a complete path for current flow
Short circuit - ANSWER-An undesirable, low resistance path for current to leave the
normal current carrying path through a load
Series circuit - ANSWER-A circuit that has two or more components connected suck
that there is only one path for current to flow
Switch - ANSWER-Any component that is designed to start, stop it redirect the flow of
current in a circuit
