Which point in Figure E5-1 best represents the impedance of a series circuit consisting of a 300-ohm resistor and an 18-microhenry inductor at 3.505 MHz?
AnswerPoint 3
At 3.505 MHz, an 18-microhenry inductor has about 396 ohms of inductive reactance. The impedance is about 300 + j396 ohms, corresponding to Point 3 on Figure E5-1.
