Determine the impedance Zx so that UAB is independent of any load
Z is. No double fractions may appear in the result.
By which component can the impedance Zx
will be realized? What value has
this component?
Note: The result Zx → ∞ is not sought.
I've used a method we were shown in class where we simply close the circuit on the left (meaning there will be wires where U is) and go from point A to point B.That would mean that these capacitors are in series. Now I've put calculated Zx like this;
Now if my algebra is not faulty we can make the denominator look like this;
After simplifying;
Now the solution should be;
I do not understand how they get to this.We've solved a similar problem like this in class and I'm pretty sure the method I used is not the problem but rather my algebra,or lack of if you will. Any insights?
Many thanks!
