physics Flashcards
what are conductors
materials that allow electric current to go through them freely
list 5egs of conductors
silver , gold , copper,steel
what is electricity
provides energy that we use in our daily lives
list 5 egs of insulators
glasses,rubber , plastic ,oil, diamond
what are insulators
materials that prevent the flow of an electron
list 5 ways to prevent electricity accidents
never climb trees near powerlines
never fly a kite near a powerline
never overload outlets
unplug unused outlets
never place electronics near water
what is a circuit
a closed part through which an electric circuiit flows
what is the direction of a conventional current flow
positive terminal energy source to negative terminal energy source
what is the direction of an electron flow
negative to positive
what does a basic circuit component include
cell, switch, wire ,bulb
what does cells supply
electrical energy
what are the 2 types of circuits
series and parallel
what is current measured in
amperes with an ammter
what is the difference between series n parallel circuits
series circuits cpnnect one after the other leaving 1 path for the currant to flow while parallel shine with the same brightness
which one is brighter [series or parallel]
parallel
