🔍 Key Concepts

• Series RLC circuit impedance and how resistance and reactance combine • How to find net reactance when inductive and capacitive reactances are both present • Converting a rectangular impedance (R + jX) into polar form (magnitude and angle)

💭 Think About

• First, determine whether the total reactance is inductive or capacitive when a 300-ohm capacitor and 600-ohm inductor are in series. What is the net reactance value and its sign? • Once you have R and X, how do you calculate the magnitude of the impedance using the Pythagorean theorem? • How is the phase angle of the impedance related to the arctangent of X over R, and what does the sign of X tell you about the angle direction?

✅ Before You Answer

• Compute the net reactance: XL - XC (or XC - XL) carefully, including the sign • Use ( |Z| = \sqrt{R^2 + X^2} ) with R = 400 ohms and your net X value; check that your magnitude matches one of the choices • Compute the phase angle using ( \theta = \tan^{-1}(X/R) ) and make sure the sign of X (inductive vs capacitive) matches the angle direction in polar form
