🔍 Key Concepts

• Series R-L-C circuit in figure C (all elements in one loop) • Formula for impedance of a series circuit: Z = √(R² + (X_L − X_C)²) • Condition of resonance when inductive reactance equals capacitive reactance (X_L = X_C)

💭 Think About

• In a series circuit, how do you combine resistance and reactance to find total impedance? • What happens to the net reactance term (X_L − X_C) when the inductive and capacitive reactances are equal in magnitude? • Once you know the net reactance, what does that do to the impedance formula and its numerical value?

✅ Before You Answer

• Confirm from the figure that the resistor, inductor, and capacitor in "C" are in series, not parallel • Compute the net reactance first: X_net = X_L − X_C, using their given values and signs • After finding X_net, plug into Z = √(R² + X_net²) and compare the magnitude you get with the listed answer choices
