Module 3.2 Resistance of air layers and surface layers
tea.ie• The total thermal resistance of a building component containing a well-ventilated air layer shall be obtained by disregarding the thermal resistance of the air layer and all other layers between the air layer and external environment, and including an external surface resistance corresponding to still air (see EN ISO 6946: 2007 Annex A).

Thermal conductivity - Saylor Academy
resources.saylor.orgThermal conductivity 2 Definitions The reciprocal of thermal conductivity is thermal resistivity, usually measured in kelvin-meters per watt (K·m·W−1). When dealing with a known amount of material, its thermal conductance and the reciprocal property, thermal resistance, can be described.Unfortunately, there are differing definitions for these terms.

poplab.stanford.eduthermal energy stored within a body but also how quickly the body cools or heats, that is, its thermal time constant τ ≈ RCV, where R is the thermal resistance for heat dis-sipation (the inverse of conductance, R = 1/ G) and V is the volume of the body. Thermal time constants can be very short

Inductance, capacitance and resistance
faculty.sdmiramar.eduresistance • Since resistance doesn’t effect phase the net of the two reactances, with the lessor subtracted from the greater, will act upon total impedance at 90° to resistance. • But since reactance is already expressed in the form of Ohms in a purely reactive circuit Ohms laws applies normally for a purely inductive or capacitive circuit.
