Given the network below, given an sinusoidal input current source (I_in) with an amplitude of 1 mA, running at 1 kHz with a phase of 0^o.

Treating the 2k resistor as a load, find the the Thevenin equivalent impedance (zTh) of the circuit connected to that load (i.e. find V_OC with the 2k load replaced by an open circuit), in terms of the component impedances (zC for the 2.2uF capacitor, zL for the 10 mH inductor, and zR for the 1kΩ resistor).

Your answer may look something like:

zTh = zC + zL +zR, or (1/zC + 1/zL + 1/zR)^-1
