일반물리학 2 — Electromagnetic Oscillations and Alternating Current: Problem 60

60 An alternating source with a variable frequency, an inductor with inductance L, and a resistor with resistance R are connected in series. Figure 31-29 gives the impedance Z of the circuit versus the driving angular frequency \(\omega_d\), with the horizontal axis scale set by \(\omega_{ds} = 3200 \text{ rad/s}\). The figure also gives the reactance \(X_L\) for the inductor versus \(\omega_d\). What are (a) R and (b) L?
