An ac generator supplies an rms (not peak) voltage of 180 V at 60.0 Hz. The generator is connected in series with a 0.50-H inductor, a 6.0-µF capacitor and a 300-$\varOmega$ resistor.
-What is the inductive reactance?
A)150 $\varOmega$
B)190 $\varOmega$
C)360 $\varOmega$
D)390 $\varOmega$
E)440 $\varOmega$

The inductive reactance, X_L, can be found using the formula X_L = 2πfL, where f is the frequency (in Hz) and L is the inductance (in H). Substituting the given values, we get X_L = 2π(60)(0.50) = 188.5 Ω. Rounded to the nearest 10 Ω, the answer is 190 Ω, which is choice B.
