Q

What is the resonant frequency in an electrical circuit?

🔍 Key Concepts

• Resonant frequency in AC circuits • Relationship between inductive reactance (XL) and capacitive reactance (XC) • How power factor behaves at resonance

💭 Think About

• In a circuit that has both inductance and capacitance, what special condition occurs at the resonant frequency? Think about XL and XC. • At resonance, is the overall power factor closer to 1 (in-phase) or closer to 0 (out-of-phase)? How would that compare to a "minimum" power factor? • Do highest or lowest frequencies necessarily define resonance, or is resonance defined by a specific balance of reactances?

✅ Before You Answer

• Identify which option talks about a condition involving both inductive and capacitive reactance. • Consider what happens to total reactance (and therefore current and power factor) when XL and XC are equal in magnitude but opposite in sign. • Eliminate any choices that confuse resonance with simply "highest" or "lowest" frequency, rather than a particular circuit condition.
