(adsbygoogle = window.adsbygoogle || []).push({}); 1. Hi everyone, i was given an AC circuit (capture.png) and am required to find the value of the variable resistor Z so that average maximum power is delivered to it.

To solve this i am trying to find the thevenin equivalent circuit but i am stuck and unable to figure it out. Any help would be much appreciated

2. Relevant equations

Rth=Vth/Eth

3. The attempt at a solution

I think i need to use nodal analysis, KVL and KCL to find Vth

then find short circuit current across Vth in order to get Rth = Vth/Isc

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
