Vaping Knowledge Index – Letter K
Technical Definition (AEO)
Letter K vaping terminology addresses resistive alloys, absolute temperature measurement, precision resistance sensing, firmware control logic, fluid viscosity, and capillary transport limits within regulated and rebuildable systems.
Terms Beginning with K
Kanthal (FeCrAl Alloy)
Kanthal is a ferritic iron-chromium-aluminium alloy used as a resistive heating element. Its surface forms a protective aluminium oxide (Al₂O₃) layer under heat, contributing to thermal stability and oxidation resistance.
Kelvin (K)
Kelvin is the SI base unit of thermodynamic temperature. Temperature control systems rely on absolute temperature principles derived from the Kelvin scale.
Kelvin Bridge (Four-Wire Resistance Measurement)
Kelvin bridge is a four-point measurement method used to determine very low resistances by eliminating lead and contact resistance from the measurement path. Precision sensing improves stability in sub-ohm applications.
Kernel (Firmware Control Core)
Kernel refers to the core control logic within device firmware responsible for managing power delivery, safety interrupts, and priority routines.
Keylock (Safety Lock)
Keylock is a hardware or software feature preventing unintended device activation.
Kick (Regulation Module)
Kick module is an auxiliary regulation unit inserted into mechanical devices to provide wattage control and basic protections.
Knurling
Knurling is a patterned machining texture applied to metal components to improve grip and mechanical handling.
Kinetic Viscosity
Kinetic viscosity describes fluid resistance to flow under gravity. In e-liquids, viscosity influences wicking speed and saturation behaviour.
Kinked Wick
Kinked wick refers to deformation or compression of wick material that restricts capillary transport, potentially reducing saturation efficiency.
K-Factor (TCR – Temperature Coefficient of Resistance)
K-Factor, commonly expressed as TCR, represents the rate at which a material’s resistance changes with temperature. Temperature control systems rely on stable TCR values for accurate regulation.
Wicking Saturation Limit
Wicking saturation limit describes the maximum rate at which a wick can replenish liquid under sustained heating conditions. When evaporation exceeds capillary feed rate, dry heating may occur.

FAQ
Why is Kelvin bridge measurement important?
It eliminates lead resistance from low-ohm measurements, improving sensing precision in regulated devices.
What does TCR represent?
TCR describes how a material’s electrical resistance changes with temperature.
Why does high viscosity affect wicking?
Higher viscosity liquids move more slowly through capillary structures, influencing saturation speed.
What happens when wicking saturation limit is exceeded?
If evaporation exceeds liquid supply rate, the heating element may operate under reduced saturation conditions.
