Admittance Formulation While some circuit theory problems are easily solved in terms of impedances, others are
easily solved in terms of admittances. This difference comes about because the rules for
combining impedances in series are simple, but for combining impedances in parallel are
complicated. The rules for combining admittances in parallel are simple, whereas the
rules for combining them when they are in series are complicated. Whichever is the best
formlation to use depends very much upon whether there is a preponderance of series or
parallel connections in the situation being analysed. It is therefore appropriate that as
well as exploring the impedance formlation as we have just done, we also in the present
section explore the corresponding admittance formulation for the solution of transmission
line problems.
We remark that in developing this formlation we are maintaining the assumption that
the lines contain no loss.
