An amplifier operating from 3V provide a 2.2V peak sine wave across a 100 ohm load when provided with a 0.2V peak sine wave as an input from which 1.0mA current is drawn. The average current in each supply is measured to be 20mA. What is the amplifier efficiency?

• A. 20.2%
• B. 25.2%
• C. 30.2%
• D. 35.2%
