Electrostatics equations.

Equation \ref{m0020_eBCE} is the boundary condition that applies to \({\bf E}\) for both the electrostatic and the general (time-varying) case. Although a complete explanation is not possible without the use of the Maxwell-Faraday Equation (Section 8.8), the reason why this boundary condition applies in the time-varying case can be disclosed here.A body in which electric charge can easily flow through is called a conductor (For example, metals). A body in which electric charge cannot flow is called an insulator or dielectric. (For example, glass, wool, rubber, plastic, etc.) Substances which are intermediate between conductors and insulators are called semiconductors.The principle of independence of path means that only the endpoints of C in Equation 1.4.1, and no other details of C, matter.
