In the circuit shown below, a three-phase star-connected unbalanced load is connected to a balanced three-phase supply of 100$$\sqrt 3 $$ V with phase sequence ABC. The star connected load has Z_A = 10 $$\Omega$$ and Z_B = 20$$\angle$$60$$^\circ$$ $$\Omega$$. The value of Z_C in $$\Omega$$, for which the voltage difference across the nodes n and n' is zero, is
