I am reading a book on circuit analysis:

*Schaum's Outline of Basic Circuit Analysis*, on page 274, Exercice 12.99, we have this circuit :

The chapter is about

*Basic AC circuit analysis*;

I know how to get the answer, which is sinusoidal without DC component (as shown above), but when i simulate this circuit (with LTSpice and Proteus 8) i am getting a sinusoid, that's OK, but it has a DC component, around -4v ? is it normal ? if yes, how can we find this DC component analyticaly ?

Thanks.
