A wattmeter is connected with the positive lead on phase “a” of a three-phase system.  The negative lead is connected to phase “b”. A separate wattmeter has the positive lead connected to phase “c”.  The negative lead of this wattmeter is connected also to phase “b”.  If the input voltage is 208 volts line-to-line, the phase sequence is “abc” and the load is 1200 ohm resistors connected in “Y”, what is the expected reading of each of the wattmeters? (Hint: draw a phasor diagram)
