Junction Rulethe sum of all currents entering a junction must equal the sum of the currents leaving (conservation of charge)Power (related to "brightness")P=IΔV or P=((ΔV)^2)/Relectromotive force (emf)εcapacitorstores charge-- becomes fully charged when its potential difference is equal to the battery's (i think)dielectric constantratio of field magnitude w/o dielectric to field magnitude inside dielectricequivalent capacitance in parallelCeq = C1 + C2 + C3 + ...equivalent capacitance in series1/Ceq = 1/C1 + 1/C2 + 1/C3 + 1/...capacitors at t=0uncharged and circuit acts like it's not present (so if it's on lone path, current would want to flow through it bc least resistance)ΔVbatt=ε-Irparallels y=mx+b ΔV=-rI+εnon-ohmicresistance not constant, usually through temperature change. graph of ΔV vs I would not be linear for deezvariable circuit componentsvalues can change
