Alternator Winding Temperature Rise in Generator
... The prime factor for a lower temperature rise in all alternators is the size and material of the steel laminations, the length of the lamination stack and the amount of copper wire used. This, added to the design of the amount of cooling air driven through the alternator, will affect the machines ou ...

An equivalent resistance is the resistance of a single resistor that
... - An equivalent resistance is the resistance of a single resistor that could replace all the resistors in a circuit. The single resistor would have the same current through it as the resistors it replaced. RE= R1 + R2 + R3 - In a series circuit, the sum of the voltage drops equal the voltage drop ac ...

... The inductance of a trace may be signifigant. For power connections, a shunt capacitor is added to counter the series inductance of a long trace. A capacitor has a low AC impedance source A 100nF capacitor is often used along with a larger capacitor. 100 nF ceramics have very low impedance at higher ...

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.
