🔍 Key Concepts

• Behavior of a parallel R-L-C circuit at resonance • Relationship between impedance and circuit resistance at resonance • Difference between series and parallel resonance characteristics

💭 Think About

• Ask yourself what happens to the inductive reactance (XL) and capacitive reactance (XC) at resonance in terms of magnitude and phase. • Consider whether the overall circuit current is maximum or minimum at resonance in a parallel circuit, and what that implies for total impedance. • Compare how the impedance at resonance behaves in a series RLC versus a parallel RLC circuit.

✅ Before You Answer

• Be clear that the question is about a parallel, not a series, R-L-C circuit. • Recall that at resonance, XL and XC are equal in magnitude but opposite in sign. • Verify whether impedance at resonance in a parallel RLC is high or low compared to the circuit resistance.
