Electrical Resistance
... If the supply e.m.f is increased but the resistance remains the same the current will increase. If the supply e.m.f remains the same but the resistance is increased the current will decrease. NOTE: It is not possible to change the resistance by changing the e.m.f or the current. The only way to chan ...

Ohm`s Law and Resistance
... The resistance of a conductor is inversely proportional to the cross-sectional area of the conductor. – Resistance decreases with increased crosssectional area. Resistance is also dependent upon the temperature of the conductor. Collisions of electrons with other electrons and with atoms raises the ...

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.
