Find V_ab and |V_ab| and the phase of V_ab.



I thought about using Thevenin, but than I thought that the elements above AB are the same as under AB.

Or I can just say that [tex]V_AB=V_source-Z_R-( V_source-Z_C)[/tex]?
How should I approach this?

I know that
Code:
[plain][tex]V_source=V_in*e^{\omega t} Z_R=R and Z_C=\frac{1}{\omega c i}[/tex][/plain]
Okay, so if you were asked merely to find the voltage at Node A, could you do it?

If you were asked to merely find the voltage at Node B, could you do it?

If so, recognize that V_ab is, by definition, the voltage at Node A minus the voltage at Node B.

I have used voltage divider is it right?

Your image capture doesn't have enough contrast for my tired old eyes to read easily, but it appears you are starting out on the right path.
