Study guide PS 102 Ch. 9-10 KEY CONCEPTS (CH.9) Electricity Atoms/protons/neutrons/ELECTRONS - Protons = Positive - Neutrons = Neutral - Electrons = Negative +Atom that loses electrons = positive +Atoms that gains electrons = negative Repulsion vs. Attraction - Like charges repel, unlike charges attract Coulomb unit 6.25 x 10^18 e- = 1 Coulomb Coulomb’s Law (inverse square law!) F = k x q1 x q2 / d2 F = Electric Force K= Constant – 9x10^9n.m^2/c^2 Q1, q2 = Charge on particle D= distance between particles Static Electricity Forces of Electrons or Deficiency of electrons + Creates difference in total charge, which promotes “flow” of electrons when opportunity arises! Polarization Charges tend to collect in order to attract other charges. Electric fields – direction of force lines? Force lines away from positive towards negative Electric POTENTIAL; POTENTIAL DIFFERENCE; EMF; VOLTAGE

VOLT = JOULE/COULOMB Potential = work/charge Potential difference is like electrical pressure! (energy!)
