I already know the values of i1, i2, i3, i4, v1, v2, v3 from doing a nodal analysis on a circuit earlier in this question which is exactly the same apart from that it contains resistors instead of capacitors and inductors.
I have the values for all the voltages and currents. I'm wondering how I go about it, given that v3 = v30 (cos (Θ3) + isin(Θ3)) and I have a value for v3. Since v3 = i4 * Z where Z is C3 and R2 in parallel, there'd still be 2 unknowns. I feel as though I'm missing something obvious, if anyone...
