🔍 Key Concepts

• Efficiency as a measure of how well input power is converted into useful output power • Difference between input power and output power in any system (like an engine, amplifier, or radio transmitter) • The idea that some power is always lost as heat or other losses in real devices

💭 Think About

• In a perfect device with no losses, what would the relationship between input power and useful output power be? • When engineers talk about "efficiency" of any machine or device, which two quantities are they usually comparing? • Look at the words input and output in each option: which one reflects how much of the input is actually turned into useful work or signal?

✅ Before You Answer

• Identify which choice compares useful output power to input power, not the other way around • Check that the ratio is set up so that efficiency will be a number less than or equal to 1 (or 100%) for real devices • Eliminate any option that does not clearly distinguish between input and useful output or that uses unclear terms like "minimum" and "maximum" without context
