Electrical Conductivity & Electrical Resistance
... made of a piece of metal that can change in length. As the length of the resistor changes, so does the resistance in the same direction. Units: The unit for resistors is the ohm, Ω. Resistance is defined as the ratio of the voltage to the current, R = V/A, where V is volts and A is current measured ...

... If one connects resistors of lower and lower value of R to get higher and higher currents, eventually a real battery fails to establish the potential difference E, and settles for a lower value. One can represent a “real EMF device” as an ideal one attached to a resistor, called “internal resistance ...

Lumped element model
The lumped element model (also called lumped parameter model, or lumped component model) simplifies the description of the behaviour of spatially distributed physical systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. It is useful in electrical systems (including electronics), mechanical multibody systems, heat transfer, acoustics, etc.Mathematically speaking, the simplification reduces the state space of the system to a finite dimension, and the partial differential equations (PDEs) of the continuous (infinite-dimensional) time and space model of the physical system into ordinary differential equations (ODEs) with a finite number of parameters.
