3.1 ‘ NODES, PATHS, LOOPS, AND BRANCHES
We now focus our attention on the current-voltage relationships in
simple networks of two or more circuit elements. The elements will
be connected together by wires (sometimes referred to as "leads").
which have zero resistance. Since the network then appears as a number
of simple elements and a set of connecting leads, it is called
a lumped-parameter network. A more difficult analysis problem
arises when we are faced with a distributed-parameter network,
which contains an essentially infinite number of vanishingly small
elements. We will concentrate on lumped-parameter networks in
this text.
