Chapter , Problem 42(choose chapter or problem)
An alternating source with a variable frequency, an inductor with inductance L, and a resistor with resistance R are connected in series. Figure 31-31 gives the impedance Z of the circuit versus the driving angular frequency vd, with the horizontal axis scale set by vds ! 1600 rad/s. The figure also gives the reactance XL for the inductor versus vd.What are (a) R and (b) L?
