1. An airfoil for a turbine engine, the airfoil comprising:
an outer wall having a pressure side, a suction side, a leading edge, and a trailing edge, the outer wall defining an interior and separating the interior from an exterior, wherein the outer wall extends between the pressure side and the suction side to define a lateral direction, between the leading edge and the trailing edge to define a chord-wise direction, and between a root and a tip to define a span-wise direction; and
multiple electrical conduits extending from the exterior into the interior along the span-wise direction, at least one electrical conduit of the multiple electrical conduits comprising:
at least one conductor forming a cooling conduit with a hollow interior having a central axis along which at least a portion of a cooling flow path extends;
wherein the at least one conductor surrounds the cooling flow path; and
wherein the multiple electrical conduits are spaced from each other a first distance in the exterior and a second distance less than the first distance within the interior.
