an electric company used two wattmeters to measure 3 phase power by a balanced lagging power factor load.. The current coils are in lines 1 and 2. The potential coils are connected across lines 2 and 3 and lines 1 and 3 respectively. The voltages are 230 volts, V12 leading V23 and the line currents are each 150A. The watteter's each indicate 19.6kW. What is the total power
