current
resistance
magnetism
electricity
The quality of a substance that hinders the flow of electrons through it; the ratio of the voltage to the electric current.
resistance
magnetism
electric potential
current
A loop of conductive material through which electrons flow continuously.
current
electricity
circuit
field
The quantity of unbalanced electricity in an object; a charge is either positive or negative and can be understood as an excess or deficiency of electrons.

up and down poles
If you have a string of lights and one light goes out but the others stay lit, which type of circuit do you have?
series
parallel
short
broken
How is a conductor different than an insulator?
A conductor does not have magnetic fields; an insulator has magnetic fields.
In a conductor, electric current cannot flow freely; in an insulator, it can flow freely.
A conductor has magnetic fields; an insulator does not have magnetic fields.
In a conductor, electric current can flow freely; in an insulator, it cannot flow freely.
