Document Summary
Law of conservation of electric charge: the net amount of electric charge produced in any process is zero (no net electric charge can be created or destroyed. Conductors allow flow of charge with free movement of electrons while insulators don"t. ; k is proportionality constant; q is magnitude of charge in coulomb"s (c); r is the distance bt charges; charge of en electron (e)=; proton is. Electric field: at any point in space is the force exerted on a tiny positive test charge divided by magnitude of test charge q () Superposition principle: if at a point there is an electric field due to more than one charge, the effective electric field (vector sum) Electric fields point out from positive charge towards negative charges. 21. 7 electric field calculations for continuous charge distributions can be used to solve for many charge distributions.
