... Electrons do not flow like water in a pipe. In the absence of voltage, they move randomly at high speeds, due to their temperature. When a voltage is applied, a very small drift velocity is added to the thermal motion, typically around 1 mm/s; this is enough to yield the observed current. ...

... Sometimes you need a kind of resistor, but you don't have it on hand and it doesn't exist. Fortunately, it's possible to use several different resistors in combination to get virtually any level of resistance, for example if you have 2 resistor of 20 Ohm and you need a resistor of 40 Ohm, just add b ...

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.
