If the output power of an amplifier is 10 V, and the input power supplied to the amplifier is 0.229 V given that the DC voltage used is
A)25%
B)50%
C)75%
D)35%

Question

Quizplus · Accepted Answer

The efficiency of an amplifier is not directly related to the input and output voltage levels but rather to the power levels and how much of the input power is converted into output power versus how much is lost as heat or in other inefficiencies. The choices provided (25%, 50%, 75%, 35%) seem to refer to efficiency percentages, but without specific information on power (not voltage) and losses, or how these percentages were derived, it's impossible to accurately determine the efficiency based on the given voltage values alone. The question appears to be malformed or missing crucial information needed to calculate efficiency.
