87. (a) We observe that ω = 6597 rad/s, and, consequently, X L = 594 Ω and X C =303Ω.S ince X L >X C , the phase angle is positive: φ =+60 . (b) From Eq. 33-65, we obtain R = X L X C tan φ = 168 Ω . (c) Since we are already on the “high side” of resonance, increasing f will only decrease the current further, but decreasing f brings us closer to resonance and, consequently, large values of I .
