Question

Problem 9. Figure 7.79 shows how the reactance of an
inductor varies with frequency.
(1) Calculate the value of the inductance of the inductor
using the information given in the graph.
(ii) If this inductor is connected in series to a resistor of
8 ohm, find what would be the impedance at 300 Hz ?
