🔍 Key Concepts

• Q (quality factor) of a resonant circuit and what it physically represents (bandwidth, losses, sharpness of tuning) • How coupling to a resonant circuit (looser vs tighter) affects its losses and effective Q • How losses in coil, capacitor, and supports affect the circuit’s Q

💭 Think About

• Think about whether adding stronger coupling to another circuit usually increases or decreases the losses seen by the resonant circuit itself. • Ask yourself what happens to Q when resistance or losses in the inductor, capacitor, or their supports go up or down. • Compare which options would tend to make the circuit ring longer (oscillate with less damping) after being excited.

✅ Before You Answer

• Recall that higher Q means narrower bandwidth and lower losses in the resonant circuit. • Decide whether tighter coupling usually causes more energy to stay in the resonant circuit or be taken out of it. • Consider whether using low-loss materials in physical construction would increase or decrease energy dissipation per cycle.
