    can anyone please help..

    how will i be able to measure the current in a plug and then transfer/export the reading(data) to a computer??

    I have done this as a three phase unit. I used a DAC and read it through the parallel port. Then wrote a VB program to display the results.

    You can use a pic microchip with ADC and a stunt resistor and send that by rs232 very easy.

    not to highjack, but I think it's related to OP's post; would using a shunt resistor give you a useful current measurement for calculating apparent power or real power?

    Not by it's self , but it's a start. You can make a nice current meter with a pic microchips ADC and send the data over rs232

    You can get the values you need
