... We wait until the system reaches the thermal steady state. After this we switch off the driving current in ms time and capture the voltage transient with ms sampling rate in logarithmic sampling mode (200 sample/octave). The temperature transient curve can be calculated from the electric transient, ...

How to Select the Right Temperature Sensor
... Here again, a current is forced through the device and the resulting voltage is measured. However, a third wire provides compensation for the lead resistance. This requires either a three-wire compensating measurement unit or actually measuring the contribution from the third wire and subtracting it ...

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.
