When the switch in the circuit is closed, then I=(3-j)A. Find complex power of Ig1 when the switch is off if we know that then, complex power of Ig2 is Sig2=(10+j6)VA.
Known values are: Z=(2-j2)Ohms , Z1=(1+j2)Ohms, Z2=Z4=(2+j4)Ohms, Z3=(2-j4)Ohms, Ig1=(0.5+j1.5)A and E=(7+j3.5)V.
In the first case, there's no impedance Z in the circuit, does it means that there's no Ig2 in the circuit since both ends of Ig2 are on the same potential or i'm wrong, i am not really sure about this because that would mean that Ig2 is zero and how then it's complex power can be (10+j6)VA?
