Q

What is the characteristic of the current flow within the parallel elements in a parallel R-L-C circuit at resonance?

🔍 Key Concepts

• Behavior of R-L-C circuits at resonance (especially parallel resonance) • Relationship between impedance and current in parallel branches • Difference between total line current and branch currents in a parallel circuit

💭 Think About

• At resonance in a PARALLEL R-L-C circuit, what happens to the reactive (inductive and capacitive) currents relative to each other? • How does the cancellation of reactive powers affect the current drawn from the source versus the currents circulating in the individual L and C branches? • Is resonance associated with a very high or very low impedance seen by the source in a parallel configuration?

✅ Before You Answer

• Distinguish clearly between source (line) current and branch currents in the L and C elements • Recall whether parallel resonance is also called "current resonance" or "voltage resonance" and what that implies • Verify how the net reactive current can be small while individual branch currents behave differently
