Suppose we have a certain length of wire that we would like to wind around a cylindrical form in a single layer of closely spaced turns to make it more compact, and we would like to minimize the inductance of the resulting coil. All the available forms have a small enough radius that the length of the coil will be much larger than its radius. Given this, we should choose the form with
A. The smallest radius. B. The largest radius. C. Any radius (the inductance will be the same). D. One needs more information to answer the question.
