Both k are boltzmann constant right ,so they cancel each other right why U haven't cancelled????.. U want to clear that capital K is thermal conductivity constant and small k is boltzmann constant..

[@Yugi0623]

Y the directions can't be 8???

[@ragi_dosa]

X, y and z axis la than electron or gas molecule movement nadakkum, including their negative axis. So totally 6 directions.

Sir PH3201 physics for civil engineering podunga sir

[@adhityaadhi9107]

Why only six directions it must be eight direction,in order to right with your concept..how??? U want tell that x,y,z has totally 6 direction means x has 2 and y has 2 and z has 2..ok bro.

Hai Sir.... Beautiful explanation Sir.
I need your help with my project Sir.
I want to find out the electrical conductivity of the tungsten carbide material (90% tungsten+10% cobalt).
Conditions:
1. My composition (90%+10%) is a novel one (there is no data like resistivity, conductivity, etc)
2. The material doesn't have any definite shape (i.e square, triangle, cylinder)
How to find out the electrical conductivity as well as the thermal conductivity, experimentally or theoretically?
if it is possible, please let me know. It will be useful for my project work.
Thank you in an advance.
keep doing your service.
