Hi you all,
I need to monitor AC current from 200mA to 5A for overload or short circuit detecting purpose. I need to make it simple and cheap. I mean to use current sensing small value resistor (0.1ohm/3W) to sense the current. Is there any kind of good precision resistor can serve this purpose? Thanks
