Quizplus · Accepted Answer

The phase angle is given by the arctangent of the ratio of the inductive reactance to the capacitive reactance. In this case, the inductive reactance is 183 V / 54 V = 3.4 and the capacitive reactance is 79 V / 54 V = 1.46. Therefore, the phase angle is arctan(3.4 / 1.46) = 63°.
