Question 1 of 27070

Unused portions of inductances in receivers are ____ to reduce any losses that might occur in these unused windings:

🔍 Key Concepts

• Inductors (coils) and how voltage is induced in windings • What happens to unused turns on a transformer or inductor if they are left electrically connected vs disconnected • How to minimize losses and unwanted signals (noise, heating, or coupling) in radio receivers

💭 Think About

• Think about what causes loss in an unused section of a coil: is it more likely due to current flowing in a loop, or due to it sitting open with no complete path? • Ask yourself: if a magnetic field cuts across unused turns, what electrical condition on those turns will prevent significant current from circulating? • Which option best matches standard radio/receiver construction practices for handling extra turns or taps on a coil?

✅ Before You Answer

• Check which option actually eliminates a closed path for circulating current in the unused turns. • Confirm which choice is a common practice in RF (radio frequency) inductors and transformers as taught in electronics texts. • Make sure the option you pick clearly reduces energy dissipation (I²R heating) in the unused windings, not just changes their physical shape or appearance.
