    In the following circuit i need to determine equivalent impedance

    I'm not really sure how to calculate that. Would I just have to add all three impedances together? Thanks.

    Yes, you do just add them because they are in series. However, you need to be careful because impedances are complex numbers that add like vectors.

    See the following.
