As f ---> 0, The phase < of the inductor approaches pi/2 The phase < of the resistor approaches 0 As f ---> infinity The phase < of the inductor approaches 0 The phase < of the resistor approaches pi/2 So the phase over the resistor definitely increases, but the overall phase angle will depend on what the previous phase angle was before you started increasing the frequency. |

I can not understand this answer. Can you provide us equations ? |

Phase angle = tan(inverse) [2pifL/R]. So f is increase then phase angle is increase. |
