Hi expert guys! i m facing a problem for my recent project "Automatic power factor correction using microcontroller" . I want to take the current sample. I used a circuit which i have attached with this thread. Please see and suggest me is it right way to take current sample? Does this circuit will damaged the ADC or not? waiting for your favorable suggestions. (please see attched file)..thankx

You do NOT want to do it this way. You will be tying your microcontoller directly to mains voltage, generally a BAD thing. It also violates the forum rules for proper mains isolation,

Look at circuits that use a current transformer to get current information.
