Source sentences:
text: The resistors use dc power and so the amplifier has low efficiency.
text: A Class A transistor amplifier has 25% efficiency and provides excellent signal reproduction but the efficiency is very low.
text: By using more power, an amplifier has less power available for the output signal; thus the efficiency of the amplifier is low.
text: A amplifiers create tremendous amounts of heat adding to their very low efficiency at around 30%, making them impractical for high-power amplifications.
