Solution

$W h e n ω > ω_{r}, w e c a n w r i t e ω > \frac{1}{\sqrt{L C}} \Rightarrow ω L > \frac{1}{ω C} \Rightarrow X_{L} > X_{C} . H e n c e t h e c i r c u i t b e c o m e s i n d u c t i v e . A l s o \tan ϕ = \frac{X_{L} - X_{c}}{R} . I n i n d u c t i v e c i r c u i t X_{L} > X_{C}, s o ϕ i s p o s i t i v e a n d h e n c e v o l t a g e l e a d e s t h e c u r r e n t .$
