    Okay.... so calculate the voltage across the inductors and find the total current.

    This is not the Homework Done For You forum.

    YOU need to show YOUR best attempt to solve YOUR homework. We can then look over your work and, if necessary, help you see where you are going wrong and help you get back on the right path.

    WBahn, since so many posters here seem to think it is a Homework Done for you forum, perhaps its name needs to be changed to "Homework Assistance (not done for you)" so they may better get the message (but no guarantee). :rolleyes:

    May not be a bad idea but, like you, I have doubts about how much difference it will make.

    Hi,

    To start, do you know how to calculate the total inductance of two inductors in parallel?

    You can simulate the circuit. This way you will know answers to 5 and 7. This will let you check your answers, if you do the math.

    To everyone else. I am kinda curious about number six. What are the criteria to decide if the circuit is predominantly resistive or inductive?

    About the only criteria that would make sense, in the lack of anything specific, would be if the resistive component is more or less than the reactive component (which is equivalent to saying if the impedance angle is less than or greater than 45 degrees (in magnitude).

    So find total impedance of the circuit, it will be complex value, find the angle from the complex value?

    That would be one way.
