Before revision: A low-pass filter as conventional discrete components connected on a printed circuit board (left), and as a distributed-element design printed on the board itself (right) Circuit modelling Distributed-element circuits are designed with the distributed-element model, an alternative to the lumped-element model in which the passive electrical elements of electrical resistance, capacitance and inductance are assumed to be "lumped" at one point in space in a resistor, capacitor or inductor, respectively.
