how to make a dc load

I need to make a variable load preferably using a potentiometer control.

Voltage is 60VDC current should be variable from 0 to 500mA?

How should be the strategy. Not to be mass produced .For testing.

Thanks

You can use a simple current sink with a MOSFET and an opamp.

I had never in anyway hinted that the documents are useless because it is not in English. I can get an idea of the method proposed from the schematics.
btw could we use web translators to translate PDF documents? Or any other tool available for that?

Thanks for the helping hand
regards
 

upload the pdf file to **broken link removed**
and then send the generated web page to google translator
may be the best free method to do that
