What does your textbook say about Example 2.2?
It is necessary to define a few terms before we consider the subject of conductance of electricity through electrolytic solutions. The electrical resistance is represented by the symbol ‘R’ and it is measured in ohm ( W ) which in terms of SI base units is equal to (kg m )/( S A ). It can be measured with the help of a Wheatstone bridge with which you are familiar from your study of physics. The electrical resistance of any object is directly proportional to its length, l , and inversely proportional to its area of cross section, A . That is, R µ l A or R = r l
