hi guys...

i need a circuit for voltage to current conversion for converting 0-5 amperes to 0-50 mA (100:1). i have tried using current transformer but i m not geting any linearity. its just impossible to design a circuit using transformer.

Assuming that you want a Voltage to Current, and not
i need a circuit for voltage to current conversion for converting 0-5 amperes to 0-50 mA (100:1)
Huh Huh Huh
You mean 0-5V into 0-50mA, rigth?

Try this simple schematic found on:
http://www.allaboutcircuits.com/vol_3/chpt_8/7.html

There is a lot of schematics on the net:
