I need to find the total impedance in a circuit that has:
j60 ohms, 30 ohms, -j60 ohms and 20 ohms in parallel
Ztotal=1/(Z1+ Z2+ Zn)
The Attempt at a Solution
I've tried doing this, but what I think is the -j60 and the j60 should cancel therefore leaving only the 30 ohms and 20 ohms in parallel, which would equal 1/50, but the answer says it is 12 ohms.
Attached is an image of the circuit and answer.
