🔍 Key Concepts

• Resonant circuit behavior in an AC system (RLC circuit) • How inductive reactance and capacitive reactance compare at resonance • The phase relationship between voltage and current when net reactance is zero

💭 Think About

• At resonance, what happens to the inductive and capacitive reactances—are they equal, or is one larger? How does that affect the net reactance? • If the net reactance of a circuit is zero, what type of circuit does it behave like overall (purely resistive, purely inductive, or purely capacitive)? • In a purely resistive AC circuit, how are voltage and current related in terms of phase angle?

✅ Before You Answer

• Verify what it means when XL = XC (inductive reactance equals capacitive reactance). • Confirm the overall impedance type (resistive/inductive/capacitive) of a resonant RLC circuit. • Recall the phase angle between voltage and current in a purely resistive circuit.
