Rheostat.

Hello,

3D models of the following had been made in Blender 2.49 version for Project OSCAR 3D model Repository and were rendered in Blender Internal Render engine.
I have re-done the material and lighting of these models in Blender 2.63 version and rendered with Cycles render engine.

 

Rheostat, adjustable resistor used in applications that require the adjustment of current or the varying of resistance in an electric circuit.. Its resistance element can be a metal wire or ribbon, carbon, or a conducting liquid, depending on the application.

UV unwrapping has been done to get the copper coil effect.

Done in Blender internal render 2.49
