Thermoelectric Sentence Examples
In 1873 he took thermoelectricity for the subject of his discourse as Rede lecturer at Cambridge, and in the same year he presented the first sketch of his well-known thermoelectric diagram before the Royal Society of Edinburgh.
We have also the relations dE/dt = b+2ct and d 2 E/dt 2 =2C. The first relation gives the thermoelectric power p at any temperature, and is probably the most convenient method of stating results in all cases in which this formula is applicable.
Becquerel that the intensity of the effect depended on the thermoelectric power of the junction and was independent of its form or dimensions.
In accordance with this hypothesis, the curves representing the variations of thermoelectric power, dE/dt, with temperature 'OObservationsof' Pia.
The general results of the work appeared to support Tait's hypothesis that the effect was proportional to the absolute temperature, but direct thermoelectric tests do not appear to have been made on the specimens employed, which would have afforded a valuable confirmation by the comparison of the values of d 2 E/dT 2, as in Jahn's experiments.Advertisement
The line of lead is taken to be horizontal in the diagram, because the thermoelectric power, p, may be reckoned from any convenient zero.
The " thermoelectric constant," 0, of Kohlrausch, is evidently the same as the thermoelectric power, p, in Thomson's theory.
It is difficult to see how this complication can be avoided, unless the first postulate is abandoned, and the heat-flow due to conduction is assumed to be independent of the thermoelectric phenomena.
The HPM incorporates drive electronics for those laser diodes with a built-in thermoelectric cooler.
The radiation passing out from an opening in the furnace falls upon a concave mirror in a telescope and is focused upon a thermoelectric couple.Advertisement
A typical thermoelectric generator (TEG) used to convert temperature differences into electrical power.
Semi conductor thermoelectric device which works on the Peltier effect.
Explain what is meant by the Peltier coefficient and thermoelectric power.
Thermoelectric materials can also be used in cryotherapy, pacemakers, and as thermocouple sensors.
Problems with thermoelectric coupling effects can also be considered.Advertisement
The single bottle chillers are designed to chill your wine by either spraying the wine bottle with jets of ice water once it is placed in the machine or through a cooling electronic current called thermoelectric cooling.
Depending on the make, model and how much you are willing to spend, there are also floor model chillers available that use thermoelectric cooling to chill its contents.
These are smaller versions of the floor models and chill your wine by thermoelectric cooling.
The second type is through thermoelectric cooling.
Thermoelectric cooling is also known as the Peltier effect.Advertisement
Their wine chiller uses the thermoelectric cooling method, comes with ten pre-set temperatures and has a reasonable price tag of $59.95.
It uses the thermoelectric cooling method to chill your bottles of wine and features a backlit LED display as well as an alarm that sounds when the wine has reached its' desired temperature.
Sunpentown WC-06 Thermoelectric wine cooler - This super-sleek wine chiller comes in a platinum finish and holds up to six bottles of wine.
It uses thermoelectric cooling so it runs very quietly and has LED temperature readout with an ultra modern stainless steel trim.
Seebeck found that the metals could be arranged in a Thermoelectric Series, in the order of their power when combined with any one metal, such that the power of any thermocouple p, composed of the metals A and B, was equal to the algebraic difference (p'-p") of their powers when combined with the standard metal C. The order of the metals in this series was found to be different from that in the corresponding Volta series, and to be considerably affected by variations in purity, hardness and other physical conditions.Advertisement
Cumming shortly afterwards discovered the phenomenon of Thermoelectric Inversion, or the change of the order of the metals in the thermoelectric series at different temperatures.
Similar phenomena occur in the case of many other couples, and it is found that the thermoelectric power p is not in general a constant, and that the simple linear formula (I) is applicable only for small differences of temperature.
A thermoelectric circuit may be cut at any point and a wire of some other metal introduced without altering the E.M.F.
For high temperature work it is necessary to employ platinum, which would be an ideal standard for all purposes on account of its constancy and infusibility, did not the thermoelectric properties of different specimens differ considerably.
But on account of the difficulty of the measurements involved, the verification of the accurate relation between the Peltier effect and thermoelectric power was left to more recent times.
The balance is adjusted by shunting either AD or BD with a box, S, containing 20 to Ioo ohms. All the wires in the quadrilateral must be of the same metal as AB, to avoid accidental thermoelectric effects which would obscure the result.
The order of the metals in respect of the Peltier effect was found to be the same as the thermoelectric series.
