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
