current

hay,

Iam doing digital display for high voltage power supply.
In this supply I want display 0-2A current & 0-1000v voltage .Iam using 0.5 ohm 2W shunt Resister, Atmega32 controller
Can any body help me how to make signal condition circuit between shunt resister & controller by using amplifiers.

Regards

There is a similar discussion in a thread called "didital ammeter"
You need to be aware that resistors also have voltage ratings as well as power ratings. I also hope you didnt chose 2W by going 2^2*.5, as although this equates to 2W - it's a dangerous practice and you should use a 5W resistor.

Thanks for the reply

I have to measure the current and voltage when 1KV,2A power supply connected to the load.

Please suggest suitable analog circuits & sites related .

Wellllll... you could buy a serious mutimeter, or as the other thread suggested a Current Shunt...

Becareful eh... thats a 2kW supply you've got going there...
