# What is the cell constant of a cell of an electrode having dimensions 4cm & 3cm and the two electrodes are separated by 2cm?

$\begin{array}{1 1}(A)\;1/3cm^{-1}&(B)\;1/6cm^{-1}\\(C)\;1/9cm^{-1}&(d)\;1/2cm^{-1}\end{array}$

Cell constant=$\large\frac{l}{A}$
$\qquad\qquad\;=\large\frac{2}{4\times 3}$
$\qquad\qquad\;=\large\frac{1}{6}$$cm^{-1}$
Hence (B) is the correct option.
