PS: Ch 15 Q

materials through which electric current does not flow easily insulators
Electric current that flows first in one direction and then the other alternating current
the amount an object hinders electron flow resistance
rate of charge flow current
SI unit of resistance ohm
flow of electrons from one place to another current electricity
states that the current flowing through a conductor is directly proportional to the voltage and inversely proportional to resistance Ohm's law
material that allows current to flow through it with no hindrance superconductor
