Actually in networks we will consider the elements like resistance, inductance, capacitance as lumped elements for simplicity, like this in power systems we will consider the transmission line parameters(resistance, inductance, capacitance) as lumped elements, because we will calculate all the parameters of power systems with respect to receiving end or sending end but not with respect to middle of the line. If a fault occurs on transmission line then we should not consider the lumped elements of that total transmission line, we should consider the lumped elements from sending end to the point where the fault is occurred.
Lumped elements in a circuit refer to components where electrical properties (resistance, capacitance, and inductance) are assumed to be concentrated at specific points rather than distributed over a physical length. This model simplifies the analysis of circuits by allowing the use of idealized components like resistors, capacitors, and inductors, which are characterized by their voltage and current relationships. The lumped element approximation is valid when the physical dimensions of the components are small compared to the wavelength of the signals being analyzed, ensuring that variations in the electromagnetic fields across the components can be neglected.
Lumped systems are those systems in which electrical properties like R, L, C etc are assumed to be located on a small space of the circuit. these systems are applicable for low frequency application. On the other hand Distributed systems assume that electrical properties R, L, C etc are distributed across the entire circuit. these systems are applicable to for high (microwave) frequency application. Unlike the lumped element model, it assumes non-uniform current along each branch and non-uniform voltage along each node.
The voltage itself will determine the direction of current (assuming there isn't another source pushing current through the source backwards); the amount of current will be determined by the thevenin equivalent resistance of the circuit connected to that source (the resistance "seen" by the source, which can be lumped into a single circuit element).
The way I have done this with things such as heaters, window defrosters, etc. is to model the heating element as a resistor (or a set of resistors in different parallel and series combinations, based on the layout). The wire used in the electric blanket (the heating elements) should have a specific resistance per length; calculate the length of the different sections, and create a lumped resistive element of this total length.
Circuit parameters can be classified as:1-- Active or Passive2-- Linnear or Non-linnear3-- Unilateral or Bilateral4-- Lumped or Distributive1-- Active or Passive:Those circuit elements that supply energy to an energised circuit are called active circit elements. Eg.: Voltage source, current source,etc.Note: It is important to note that dependent sources cannot be placed under this category as they depend on the value of current or voltage in any other branch of the network.Passive circuit elements, on the other hand, are those elements that use up the energy supplied by the active sources and\or do not supply their own energy to the circuit.Eg.: Resistor, capacitor, inductor, etc.Note: It is important to note that a capacitor does store energy and also supplies it back to the circuit but this energy is not of its own, instead it's the energy supplied by some active component. Hence, it cannot be placed under the category of active circuit parameters.Thus an energised network(or a circuit) consists of both active and passive elements.2--
Lumped element resonators use discrete components like capacitors and inductors to create resonance, whereas distributed element resonators use transmission lines to create distributed capacitance and inductance throughout the structure. Lumped element resonators are typically smaller and easier to design but have limited bandwidth compared to distributed element resonators, which are larger but offer wide bandwidth and better performance at higher frequencies.
The circuit is callaed lumped circuit whose elements can seprate(eg rectifier circuit in pcb). but in the distributed circuit we can seprate the elements from the circuit(eg transmision lines)
transmissionline is a distributed element
A lumped circuit is a circuit where the physical dimensions of the components are small compared to the wavelength of the signals being used. It allows for simplified analysis without considering the distributed nature of the circuit. Components in a lumped circuit are represented as single points.
lumped" means that the dimension of you ckt element is much smaller than the wavelength of the signal passing through it. Therefore, you can treat your ckt element as a lumped unit (against the wavelength), and do not have to worry about wave propagation phenomenon "within" your ckt element. The opposite of "lumped element" is "distributed network." Typically, in low-frequency ckt/network, since the frequency is low, therefore, the wavelength is large (wavelength = propagation speed(usu. speed of light) / frequency ), so most elements can be treated as lumped. However, as frequency goes higher and higher, the wavelength becomes shorted and shorter, the wave propagation effect WITHIN the ckt element becomes more and more pronounced.

The voltage itself will determine the direction of current (assuming there isn't another source pushing current through the source backwards); the amount of current will be determined by the thevenin equivalent resistance of the circuit connected to that source (the resistance "seen" by the source, which can be lumped into a single circuit element).
