Internal Resistance
... thinking about potential dividers for a second, you should realise that so long as the components in the circuit have quite large amounts of resistance, then the comparitively small amount of resistance found in copper wires will be insignificant, and need not worry us. In these circumstances, we ca ...

... The resistor is normally in contact with the air, so its increased temperature will result in a transfer of energy by heat into the air. The resistor also emits thermal radiation. After some time interval, the resistor reaches a constant temperature. The input of energy from the battery is balance ...

RTD Theory
... So what exactly is an RTD? An RTD is a device which contains an electrical resistance source (referred to as a “sensing element” or “bulb”) which changes resistance value depending on it’s temperature. This change of resistance with temperature can be measured and used to determine the temperature o ...

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.
