Consider a series RLC circuit like the one shown in Figure 30.13. The cir- cuit is driven at an angular frequency w by the time-varying emf. The resonant angular frequency is wo. Decide whether each of the follow- ing statements is true or false. a) If w=wo, the voltage and the current are in phase. b) If wwo, the voltage lags behind the current. c) If w > wo, then Xc> XL. ww R moms L V? emf C FIGURE 30.13 A single-loop circuit containing a source of time-varying emf, a resistor, an inductor, and a capacitor.
