Answer»

1. The quantity ℓ/A is called cell constant.

A = Area of cross section of the electrodes.

ℓ = distance of separation of two electrodes.

2. Specific conductance = Cell constant × Conductance

3. Cell constant = Specific conductance × Resistance

= 0.0075 ohm 1 cm^-1 × 100 ohm = 0.75 cm^-1
