The input signal in a class C circuit is amplified to get a large output power with an efficiency approaching
A) 15 percent.
B) 50 percent.
C) 75 percent.
D) 100 percent.

Question

Quizplus · Accepted Answer

Class C amplifiers can achieve efficiencies approaching 100% because they operate by switching, thus minimizing the time during which current flows through the transistor, which in turn minimizes power loss.
