The possible connection of the ballistic diffusion with diffusion of ions through ion channels is discussed. For the flashing ratchet model we find that there is a current inversion in the variation of the current with half cycle period which accounts potential on-off operation. The current inversion disappears if one switches from non-Gaussian to Gaussian noise. The phenomena of current inversion is also found to occur as the asymmetric character of the ratchet potential grows. On increasing noise correlation time ($\tau$) mean velocity of a particle first increases and then decreases after passing through a maximum if the noise is non-Gaussian. For Gaussian noise current monotonically decreases. The current is enhanced if the noise is more departure from Gaussian behavior.
