electricity at rest
electrical forces
pair of attractive/repelling forces from atom particles
atoms
positively charged nucleus with negatively charged electrons
like charges repel, opposites attract
fundamental rule of electrical forces
ion
charged atom
conservation of charge
electrons are not created nor destroyed, only transferred
coulomb
SI unit of charge, abbreviated C
conductors
surfaces w/ “loose” electrons, free to roam in material and not anchored to nucleus
insulators
electrons tightly bound, poor conductors of electricity and heat
semiconductors
materials that can be made as insulators or conductors
superconductors
materials with 0 resistance to flow of charge
charging by contact
transfer of electrons by touching
induction
charging of object without contact
grounding
charge moves off/onto conductor by touch
electrically polarized
1 side of atom/molecule more charged, induced
electric dipole
more negative charge on 1 side than the other
