1) N cells are there with a resistance of R in each of them
if they are all connected in series, maximum resistance will be : N R
if they are all connected in parallel, then minimum resistance = R / N
2) temperature, material type , number of conduction electrons available in the atom, length , area of cross section. resistivity of the material
