Capacitive-resistive transients in terms of field quantities

Abstract

Capacitive-resistive transients in extended media are discussed in tenns of electric field quantities. Obviously, in these problems, the contribution of the magnetic field to the electric field is deemed negligible. For a simple lliustrative example, the field solution is compared with the circuit-theoretical result for the voltage and current. An algorithm for solving such transients in space and time domain with the help of a Laplace solver is presented. Any other Laplace solver can also be used for this purpose. Its applicability is demonstrated with the examples, one of which is chosen to have a circuit-theoretical solution.
