    I am studying for a Job placement exam I am taking tomorrow and these are the only 3 questions I cannot wrap my head around on the practice exam, can someone please help??

    1.What is the impedance of a series combination of 100 ohms and 10μF with a source of 60 Hz?

    a.100.5
    b.1000
    c.283.61
    d.265.39

    2.If a resistor of 5000 ohms is placed in series with an inductor of 10 henrys on a 120 volt line with 60 hertz, what is the phase angle?

    a.89.9°
    b.37°
    c.28.39°
    d.42°

    3. If the series resistance is 500 ohms and the capacitive reactance is 500 ohms, what is the phase angle?

    a.360
    b.180
    c.90
    d.45
