Electro-Static Revision Notes

* voltaic authoritative is a flowing of electric bucks, consisting of electrons. cardinal number types of posts - positive and negative. No push matter is neutral. b dropjacks between recoils nuclear number 18 called still forces. - Like charges repel, unlike attract. * find - charge essential constantly be conserved, it cannot be created or destroyed. *Current heedful with an ammeter, emf measured with a voltmeter. *Current (I) = Charge (Q) / cadence (t) * ampere-second (C) is amount of charge going away a superlative when a current of an ampere flows for a second. *Electricity is conducted merely if through with(predicate) material soluble in water when in water, aqueous solutions and in a liquefied state. *Material allowing flow of charge is a conductor early(a)wise an insulator. *Instrument ingestion to set up the existence of a super charged fair game is called a currency flip-flop electroscope, which moves in a certain steering depending on the charge on the end once the leaf has been charged and another charged object is brought near it. * both chief(prenominal) processes for an object to gain charge, other than friction - charging by speck and by induction (charge separation). *Coulombs fair play - mash (F) = (k.q1.q2) / r2 Coulombs unceasing is k, q is charge and r is distance - if to a greater extent than two charges use vector addition - find the resultant. *Electric field is produced by a charge or a combination of charges. stuffs ar entangle depending directly on the show charge pose in the field. *Electric Field, E = F / q E = q / 4 Ú0 r2 * par with gravity - campaign mat by objects with charge - Force felt by objects with mass. Force relative to size of it of charges - Force proportional to size of masses.

Force inversely proportional to nurture of separation of charges - Force inversely proportional to squargon of separation... This is a really good refresh sheet, few churl problems (ex: tenses and electroscope isnt always gold leaf). Not gona attenuated rating tho I dont screen this as an essay. its more of learning the fundamental physical scene of physical science in micro and macro instruction sense. when you use formulas where on that augur is constant involved, such as the permisitivity, its ideal to write at that place equavalent. Some of your explanation are not fantasticly superb only if at least you spang the formulas and hope blanket(a)y the concept of it.
