The total impedance of a series AC circuit with an inductive reactance of 24 ohms, a resistance of 16 ohms, and a capacitive reactance of 16 ohms is:

🔍 Key Concepts

• Impedance in series AC circuits and how resistance, inductive reactance, and capacitive reactance combine • The formula for net reactance when both inductive and capacitive reactances are present • Using the Pythagorean theorem to find total impedance from resistance and net reactance

💭 Think About

• First, determine the net reactance from the given inductive and capacitive reactances. Are they added or subtracted in a series circuit? • Once you have the net reactance, think about how to combine it with the resistance: Do you just add the ohms directly, or do you treat them like the sides of a right triangle? • After calculating the magnitude of the impedance, compare your numerical result carefully with the choices given.

✅ Before You Answer

• Be sure you used X_net = X_L − X_C (or the reverse, depending on which is larger) for the reactances, not simple addition • Confirm you squared the correct values and took the square root of the sum of squares for impedance • Verify that your final value (in ohms) matches one of the options; if it does not, consider whether "None of the above" may be appropriate
