An alternating source with a variable frequency, a capacitor with capacitance C, and a resistor with resistance R are connected in series. Figure gives the impedance Z of the circuit versus the driving angular frequency w d; the curve reaches an asymptote of 500??, and the horizontal scale is set by w d s = 300 rad/s. The figure also gives the reactance XC for the capacitor versus w d. What are?

(a) R and

(b) C?
