we been asked to design a simple electronic wattmeter on the breadboard which measures true power, apparent pwer, rms current,rms voltage & power factor. im lookin for a simple schematic of the wattmeter circuit....to be used, this has to measure current and voltage separately and a code will be written on matlab to achieve the measurent of power, serial comms or an LCD will be used to display the measured values, microcontroller used will be the ATMega16!
