    EDIT: I'm sorry, I asked the incorrect question!! Corrected information below!!

    Hello, I got a question about how can I find the Voltage of the Inductor.

    Anyway, here's the circuit; (circ2 on the attachment)

    Since, I want to find the voltage across the Inductor, I can eliminate the V source, R1 and R2, right?

    So, my new circuit will look just like circ2.1 on the attachment.

    Now, from previous calculation, I know that the current that pass through the inductance is 1.6 A, and the voltage of the capacitor is 3.2 V

    Now, how can I calculate the voltage of the Inductor?

    What I did was, since I know the V of the capacitor, I would just need the voltage of the resistance to calculte the voltage of the inducatence, right?

    So, Vi = Vc - Vr

    Vr = 1.6 * 2 = 3.2 V therefore,

    Vi = 3.2 - 3.2 = 0 V

    Is that right, anyone?

    Any help will be gladly appreciated.
