Hi I'm sugu from Malaysia perusing degree in electrical engineering. I am doing project to measure house hold electricity appliances reading by using ct clamp. But my ct clamp read current rating,plan to use arduino Ic to measure my output from ct clamp.Could anyone suggest how to feed current source to voltage?

The output from the CT is an AC voltage across its burden resistor . You will need to convert this to DC before you can measure it .

You will need some electronics to do this  as the voltage drop across a diode bridge will make youvreading inaccurate . Google precision rectifier .
