The '''lumped-element model''' (also called '''lumped-parameter model''', or '''lumped-component model''') is a simplified representation of a physical system or circuit that assumes all components are concentrated at a single point and their behavior can be described by idealized mathematical models. The lumped-element model simplifies the system or circuit behavior description into a [[Topology (electrical circuits)|topology]]. It is useful in [[electrical network|electrical systems]] (including [[electronics]]), mechanical [[multibody system]]s, [[heat transfer]], [[acoustics]], etc. This is in contrast to [[distributed parameter system]]s or models in which the behaviour is distributed spatially and cannot be considered as localized into discrete entities.
