  2. Potentiometer - Wikipedia

    en.wikipedia.org/wiki/Potentiometer

    A potentiometer with a resistive load, showing equivalent fixed resistors for clarity. The potentiometer can be used as a voltage divider to obtain a manually adjustable output voltage at the slider (wiper) from a fixed input voltage applied across the two ends of the potentiometer. This is their most common use.

  3. Potentiometer (measuring instrument) - Wikipedia

    en.wikipedia.org/wiki/Potentiometer_(measuring...

    The principle of a potentiometer is that the potential dropped across a segment of a wire of uniform cross-section carrying a constant current is directly proportional to its length. The potentiometer is a simple device used to measure the electrical potentials (or compare the e.m.f of a cell).

  5. Thermal conductivity measurement - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductivity...

    The heat generated dissipates into the sample on both sides of the sensor, at a rate depending on the thermal transport properties of the material. By recording temperature vs. time response in the sensor, the thermal conductivity, thermal diffusivity and specific heat capacity of the material can be calculated.

  6. Specific heat capacity - Wikipedia

    en.wikipedia.org/wiki/Specific_heat_capacity

    In thermodynamics, the specific heat capacity (symbol c) of a substance is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. It is also referred to as Massic heat capacity or as the Specific heat.

  7. Thermodynamic potential - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_potential

    They can be better interpreted as the potential to perform "useful work", and the potential can be wasted. [7] Thermodynamic potentials are very useful when calculating the equilibrium results of a chemical reaction, or when measuring the properties of materials in a chemical reaction. The chemical reactions usually take place under some ...

  9. Heat capacity - Wikipedia

    en.wikipedia.org/wiki/Heat_capacity

    The heat capacity of an object, denoted by , is the limit =, where is the amount of heat that must be added to the object (of mass M) in order to raise its temperature by . The value of this parameter usually varies considerably depending on the starting temperature T {\displaystyle T} of the object and the pressure p {\displaystyle p} applied ...
