I have raw material for making Compact-Choke for flourscent
lamp of 40 Watts. We are suppose to get 0.4 amps output at
end. but we are getting 0.42 or 0.44 amps and above. We
have done many testings in different but nothing worked out.
Please suggest me how to get the correct output.

We are using 1. core winding of 700 windings of aluminium
2. E-shape iron fillings and I-shape iron fillings to
surround the winding.
