Mathematical language of field theory,r pictorial forms used in Chapter 1 into an instrument of great precision. Such a theory will consist of equations of some kind that are sufficient to define all the spatial and temporal variations of a field when the sources of the field are known, or when some other equivalent information is given

Electrostatics,ons to particular areas. The simplest applications to consider first are those involving distributions of electric charge and current which are constant in time. On putting all time-dependent terms in (3.1) equal to zero, Maxwell’s equations separate into two pairs of equations, each pair giving a s

Electrical properties of materials,gligible internal heating. Such materials can show electric properties dominated by the polarisation of bound charge as described in Chapter 6, section 6.2. When this situation applies, the materials are often called ..

A.C. Circuits,ndence. One property that makes sinusoidal time dependence specially important derives from the mathematical fact that the differentiation or integration of a sinusoidal waveform gives another sinusoidal waveform. Thus, because for linear circuit elements.if the current . varies sinusoidally in time
