The subject of electrical impedance is on the syllabi of most undergraduate courses in physics and
\nelectrical engineering. For example, Richard Feynman in his famous undergraduate text Lectures on
\nPhysics shows how to calculate the impedance of an infinite LC ladder. However, the formula he
\nobtains has no useful physical interpretation if considered in the steady state frequency domain. In
\nfact the value of this impedance becomes infinite unless one assumes that the energy flow along the
\ninfinite LC ladder is spatially uniform and in one direction only. This ad-hoc assumption, which
\nrenders the solution non-causal, is entirely unnecessary if the problem is considered in the time
\ndomain. It is important for students to appreciate that the concept of impedance works well only in
\ndissipative circuits where the effects of transients are largely short lived. The purpose of this
\npaper is to show that the same problem treated in the time domain by the Laplace transform method
