static electricity. a buildup of electric charge on the surface of an object. electromagnetic force. one of the four fundamental forces of nature; the electromagnetic force consists of static electricity, moving electricity and magnetism.
A lecture note style textbook intended to support the second semester (primarily the dynamical portion, little statics covered) of a two semester course of graduate Classical Electrodynamics.
Our aims in teaching Physics 122. To help you understand the physical basis of electromagnetism. To teach you how to solve problems involving forces, fields and energies created by electric charges and currents.
– Introduction to circuit theory: general formulation of KCL and KVL, power conservation, branch relations – Circuits with linear elements and ideal sources: node voltage analysis, superposition, Thevenin and Norton equivalents, maximum power transfer, load line analysis – Small signal models and circuit analysis
The electric potential energy for 1C of charge is the voltage (electric potential), which is 1.5 V. Thus, for 7200C of charge at a terminal. This is the total electric potential energy of the battery. Materials can be grouped in terms of their electrical characteristics as: Conductors, Insulators,and semi-conductors.
Revision Notes. R.D.Pilkington Introduction. Current: DIRECT CURRENTS. Rate of charge flow, I = dq/dt. Units: amps. Potential and potential difference: work done to move unit +ve charge from point A to point B. . Potential=Work/unit charge, Units: volts. Electric field: Force which acts on a unit +ve charge at a particular point.
