What is the effect of dilution on the equivalent conductivity of a strong electrolyte?

What is electrical resistance? Give a note on it.

Which among the following is the $CORRECT$ formula for the determination of cell constant?

The conductivity of a centimolar solution of $KCl$ at $25^{\circ} C$ is $0.0210 \, \Omega^{-1} cm^{-1}$ and the resistance of the cell containing the solution at $25^{\circ} C$ is $60 \, \Omega$. The value of the cell constant is $......... \, cm^{-1}$.

$A$ conductivity cell with two electrodes (shaded sides) is half-filled with an infinitely dilute aqueous solution of a weak electrolyte. If the volume is doubled by adding more water at a constant temperature,the molar conductivity of the cell will -

$A$ solution of concentration $C \ g \ equiv/L$ has a specific resistance $R$. The equivalent conductance of the solution is
