PHYS 1502Q Chapter Notes - Chapter 7: Farad, Equipotential, Charge Density
Document Summary
Energy stored in a capacitor when it is charged. Conductors are equipotentials, every point at the surface or inside, are at the same potential. Potential difference between any two points in a conductor: 0 = 0 (entire conductor is an equipotential) Equipotential lines are perpendicular to field lines. Solid spherical conductor a: charge q, radius. Solid spherical conductor b: charge q, radius. When connected, system acts as one conductor, charge flows from a b until. Charge density is largest at points of largest curvature producing the largest electric field at those points. Uncharged conducting shell with point charge of +q in the center. Presence of point charge causes charge on the surfaces of the shell with rearrange itself so that einside shell = 0. Induced charge of the shell due to point charge. If the point charge is moved to the right, the inner induced charges will rearrange itself so that einside shell = 0.
