Here is my solution (first I found out the resistances of the capacitors/inductors with omega as 50, then found the total current in the circuit, and then Va by summing up the voltages from the + terminal to the -ve terminal):
60<20 + I(2 - 2j + 2.5j + 4j + 5 + 5j) + 100<0 = 0
Calculator gives I as 13.37<-46.14
Va = I(-2j + 2.5j + 4j + 5) + 100<0
Va = (13.37 < 46.14) (7 + 4.5j) + 100<0
Va = 163.31 < 41.94...
What exactly have I done wrong and what would be a good way to solve this question? Also tried a bunch of different things, always get some wrong answer.
