The spectroscopic parameters of $B_c$ and the $c\\bar c$ states deduced using the phenomenological coulomb plus power form of the $q-\\bar q$ potential $(CPP_\\nu)$ with power index $\\nu$ have been employed to compute the Isgur wise function as well as the decay form factors. The universal behaviour of the Isgur-wise function at the maximum momentum transfer has been observed for different choices of $\\nu$ between 0.5 to 2.0.
