Lumped Circuit Theory - wykład

Lumped Circuit Theory It is now appropriate to review the principles of that circuit theory, designated herein
as lumped circuit theory as it has been studied at Levels 1 and 2, to recognise that
the assumptions underlying that theory are rarely satisfied, and to appreciate the need
for a form of circuit theory, to be known herein as distributed circuit theory, of wider
applicability.
The picture which will emerge is that the complete laws of electrodynamics are as
just stated in Maxwell's equations, whereas the forms of circuit analysis studied so far,
and to which on account of their simplicity and apparent sufficiency we may have become
attached, is merely an approximation with quite limited validity.
