Solve the wye-wye system circuits problem.

Image text transcribed for accessibility: A balanced three-phase wye-wye system has 60 Hz phase sources of 660 Vms . These sources deliver a total of P3 = 7200 Watts to a balanced three-phase load through line impedances of Znine Each phase impedance of the load consists of a series combination of a 15 Ohm resistor and L-Henry inductor. Find L - the value of the inductor when ZNine= 0+j0 Ohm
