Final answer:
The phase angle between the voltages of the inductor and capacitor in an RLC series circuit can be found using the formula phase angle = arctan(XL - XC)/R.
Step-by-step explanation:
In an RLC series circuit, the phase angle between the voltages of the inductor and capacitor can be found using the formula: phase angle = arctan(XL - XC)/R. Here, XL represents the inductive reactance and XC represents the capacitive reactance.
Since the phase angle is given as 45°, we can calculate the values of XL and XC using the given frequency and values of the inductor and capacitor. Once we have those values, we can substitute them into the formula to find the exact phase angle.
Therefore, we can determine that the correct answer is B. 45°.
