<p> 1. Static Electricity 2. Static Electricity Static electricity (elektrostatic) is a collection oflarge amounts of electric charge, the static (noflow), but in case of discharging the charge timeis very short. Klik ditengah layar 3. A. How Generates Electricity Charged Objects ElectricallyExample :charged object is anobject that haveexcess or shortageof electrons. Somesimple ways tocreate staticelectricity are: 4. B. Types of Electrostatic Discharge Getting a positiveIn the atom consists of aelectric charge onnucleus and electrons. an object byThe nucleus consists ofinductionprotons and neutrons,positively chargedprotons and unchargedneutrons (neutral). AtomNetralis called neutral if thenumber of protons in thenucleus equals thenumber of electronssurrounding the nucleus.Positive atom is an atomthat has more positivecharge than negativeBumicharge. 5. C. Coulomb lawCharles Augustin de Coulomb was the first to examine the relationshipwith the two charge electric force and the distance between them byusing a torsion balance. In that study ultimately concludes Coulumb in alaw called the law of Coulumb: large repulsion ataugaya attraction between two electrically chargedobjects, is directly proportional to the respective electric charge andinversely proportional to the square of the distance between the twocharged objects.Mathematically, Coulombs law can be formulated:F = gaya coulomb ( N ) q1 q 2 q = muatan ( C )F k 2 r = jarak ( m )r k= ketetapan 9.109Nm2/C2 6. D. Electric inductionElectrical induction or influensi inducedcharge separation event electricity iselectricity (electron transfer) as approachedby electrically charged objects. 7. E. Electric fieldThe electric field is the E F E Qqk 2area surroundingqr qelectrically chargedobjects are influencedby electric force. TheQ E k 2magnitude of electric rfield strength can be E = medan listrik ( N/C )determined by theQ = muatan sumber ( C )formula: q = muatan uji ( C ) r = jarak dari benda ( m )F = Gaya ( N ) 8. F. Electric potential Electric potential is the effort needed to move electric charge from one place to another by the amount of cargo. Electrical potential is formulated: WV= Q</p>
