Question

define specific conductance and give its relation with specific resistance

Answer 1

the property or power of conducting heat, electricity, or sound.

Also called specific conductance. Electricity . a measure of the ability of a given substance to conduct electric current, equal to the reciprocal of the resistance of the substance. Symbol : σ

Answer 2

ANSWER:

Specific conductance is used to measure the ‘ability to conduct electricity’ in the electrolyte solution during the process of electrolysis.  

EXPLANATION:

• Specific conductance is also referred as conductivity. Higher the concentrations of dissolved salts in water the more the conductivity. It is measured in “Siemens per meter”.  It is said to be the reciprocal of resistance.

$\bold{\text{Conductance} =\frac{1}{\text {resistance}}}$

• On the other hand, resistance of the conductor depends on its length and is “inversely proportional to its cross sectional area”. Its unit is ohm. The material’s resistance also depends on its nature and temperature.  

$\bold{\text{Resistance} =p \times \frac{l}{A}},$

• P= specific resistance, l= length of conductor, A= cross sectional area
