resistance is the obstacle that is confrontd by current in its path of travel..
it is measured using ohm scale
specific resistivity is resistance times the ratio os its length and area of cross section...
resistance is the obstruction provided in the flow of current.
voltage=current*resistance
resistance is also directly proportional to cell constant(l/a)
so introducing constant of proportionality we write p(specific resistance)
