General Information
charging methods:(basic electrostatics) by conduction: temporary vs residual charges charging by induction: temporary vs residual charges electrification by friction positively charged: loss of electrons (|e| = 1.6 x 10-19 C) inverse square relationships (Coulmb's force and E fields for point charges) inverse relationships (voltage for point charges) charges flow from one location to another because of a difference in potential charge configurations comparing net E and net V at a common point radial electric fields (point charges) direction of field lines: positive charge, negative charge, similar charges, unlike charges uniform electric fields (parallel plates) battery notation: long line positive, short line negative field strength: density of field lines or closeness of equipotential surfaces conductor vs insulator Faraday's Ice Pail Experiment conducting shells
