Optical spectroscopy was used to study the electrodynamics and hidden transport properties of a BaFe1.91Ni0.09As2thin superconducting film. We analyzed the normal state data using a Drude-Lorentz model with two Drude components one narrow (D1) and another broad one (D2). In the superconducting state, two gaps with 2Δ(2)0/kBTc= 1.9-2.0 and 2Δ(1)0/kBTc= 4.0-4.3 are formed from the narrow component D1while the broad component D2remains ungapped. The calculated total DC resistivity of the film and the low-temperature scattering rate for
