What is conductivity ? Give note on it. |
|
Answer» Solution :* Conductivity (G) : The inverse of resistance (R) is called CONDUCTANCE (G). `therefore G=(1)/(R)=(A)/(rhol)=k((A)/(l))` Conductivity=`(1)/("resistance")=(1)/("resistivity "rho)((A)/(l))` `k=(1)/(rho)=(1)/("resistivity")` * SI unit of conductivity G : The SI unit of conductance is siemens, represented by the symbol .S. and is equal to `OHM^(-1)` (also known as mho) or `Omega^(-1)`. `1S=ohm^(-1)=1Omega^(-1)=1mho` * Conduction of CURRENT is LESS due to resistance of ions present in electrolytic cell. |
