🔍 Key Concepts

• Series AC circuit impedance combining resistance (R) and reactive components (X_L, X_C) • Use of the Pythagorean theorem when resistance and reactance are at right angles in the impedance triangle • Effect of zero capacitive reactance on total reactance

💭 Think About

• How do you combine resistance and reactance in a series AC circuit when they are perpendicular quantities, not in the same direction? • If capacitive reactance is zero, what is the net reactance of the circuit, and how do you combine that with the resistance to find total impedance? • Which formula involving R and X gives you the magnitude (not the angle) of the impedance?

✅ Before You Answer

• Write the correct formula for magnitude of impedance in a series R–L–C circuit • Substitute R = 6 Ω and X_L = 17 Ω, X_C = 0 Ω carefully and compute step-by-step • Check whether your result is closest to one of the multiple-choice options before selecting your answer
