🔍 Key Concepts

• Resonance in a series R-L-C circuit • How impedance changes with frequency in a series R-L-C circuit • Relationship between impedance and current for a given applied voltage (Ohm’s Law)

💭 Think About

• At resonance, what happens to the inductive reactance and capacitive reactance relative to each other? • If total reactance cancels out at resonance, what does that do to the circuit’s overall impedance compared to off‑resonant conditions? • For a fixed AC supply voltage, how does current change when the circuit impedance is smallest vs when it is largest?

✅ Before You Answer

• Confirm what the net reactance (XL − XC) equals at resonance in a series R-L-C circuit • Think about whether the impedance at resonance is greater than, less than, or equal to the resistance R alone • Relate the resulting impedance at resonance to whether current is larger or smaller than at other frequencies
