Homework Help: Finding the voltage across capacitor (RLC circuit)

    1. The problem statement, all variables and given/known data
    This is just an example from the book.
    See images.

    I am not sure how they found v(cap) to be equal to 97.3 V.

    2. Relevant equations

    Nodal Analysis

    3. The attempt at a solution

    3 A - i(ind)/48 - i(res)/100 = v(cap)

    Too many unknowns, that's why I think I'm way off base.

    Your last equation has differing units in each term: amps, amps/ohms and volts. Not good.

    Multiply the current source by the total effective resistance the source sees, what voltage do you get?
