What happens when the solution of an electrolyte is diluted?

What is the conductivity of $0.05 \ M$ $NaOH$ solution having resistance $31.5 \ \Omega$ and cell constant $0.315 \ cm^{-1}$?

Which of the following expressions for conductivity of a solution of an electrolyte is $NOT$ correct?

Conductivity of a solution is directly proportional to

At $298 \ K$ the molar conductivities at infinite dilution $(\Lambda_m^{\circ})$ of $NH_4Cl, KOH$ and $KCl$ are $152.8, 272.6$ and $149.8 \ S \ cm^2 \ mol^{-1}$ respectively. The $\Lambda_m^{\circ}$ of $NH_4OH$ in $S \ cm^2 \ mol^{-1}$ and $\%$ dissociation of $0.01 \ M \ NH_4OH$ with $\Lambda_m = 25.1 \ S \ cm^2 \ mol^{-1}$ at the same temperature are

Why does the conductivity of a solution decrease with dilution?
