Abstract

In the theory of electrical chains is customary to assume that the capacities and inductances are the reactive elements which cannot accumulate energy However this point of view is not accurate since under specific conditions both the capacity and inductance can accumulate energy In addition to this it occurs that the capacity and inductance can play the role of effective resistance which depends on time At present wave equations for the long lines require the knowledge second derivative voltages and currents which are extended in such lines However there are such cases when such derivatives cannot be determined This is the case when dc power supply is connected to the line or when this voltage changes according to the linear law Answer to a question as one should enter in this case give in the proposed article The properties of long lines are characterized by such parameters as linear capacity and inductance which do not consider the kinetic properties of charges
