🔍 Key Concepts

• Behavior of a series R-L-C circuit at resonance • Relationship between inductive reactance (XL), capacitive reactance (XC), and impedance at resonance • Role of resistance (R) as the only opposition to current at resonance

💭 Think About

• At resonance in a series R-L-C circuit, what happens to XL and XC relative to each other? • Once XL and XC interact at resonance, what part of the circuit is left to limit the current? • How would the total impedance compare numerically to R, XL, and XC when the circuit is exactly at resonance?

✅ Before You Answer

• Verify what XL and XC are in terms of frequency (how do they change as frequency changes?). • Confirm what condition defines resonance in a series R-L-C circuit (relationship between XL and XC). • Check which element (R, XL, or XC) actually determines the net impedance at that resonant condition.
