🔍 Key Concepts

• Class A vs Class B vs Class C amplifier efficiency (how they compare) • Difference between theoretical maximum efficiency and practical/approximate efficiency • Why 100% efficiency is not realistic in real electronic devices

💭 Think About

• First, recall roughly which amplifier class (A, B, C) has the highest efficiency and which has the best linearity. • Think about whether a Class C amplifier is normally used for audio or for RF/transmitters, and what that implies about its efficiency range. • Compare each choice with what you know about typical efficiencies: which values are more common for Class A and Class B amplifiers, and which would fit a more efficient Class C amplifier?

✅ Before You Answer

• Eliminate any option that suggests perfect (lossless) performance because that is not realistic. • Check which option is clearly lower than Class B’s usual efficiency; that would not make sense for Class C. • Ask whether the remaining value is a realistic, approximate practical efficiency (not just a theoretical extreme) for a high‑efficiency RF power amplifier.
