일반물리학 2 — Electromagnetic Oscillations and Alternating Current: Problem 39

39 In Fig. 31-7, \( R = 25.0 \text{ \Omega} \), \( C = 4.70 \text{ \mu F} \), and \( L = 25.0 \text{ mH} \). The generator provides an emf with rms voltage \( 75.0 \text{ V} \) and frequency \( 550 \text{ Hz} \). (a) What is the rms current? What is the rms voltage across (b) \( R \), (c) \( C \), (d) \( L \), (e) \( C \) and \( L \) together, and (f) \( R, C, \text{ and } L \) together? At what average rate is energy dissipated by (g) \( R \), (h) \( C \), and (i) \( L \)?
