charges are ____ in a system
conserved
conductor
charges move freely, electrostatic equilibrium reached almost immediately, excess charge @ surface. ex: metals, ionic solutions
insulator
charges do not move freely, concentration of charges, easy charging. ex: rubber, glass, organic material
friction
rubs objects together to move electrons, done w/ insulators
conduction
objects touched to conductor and charges flow to reach equilibirum
induction
charges moved just from being nearby neutral conductor
value for one proton/electron
1.6 × 10^-19
k equals…
9 × 10^9
positive charges
face away
negative charges
face towards
electric field
area around a particle affected by charge
