A certain amplifier has an input voltage of 100 mV rms, an input resistance of 100 kohms, and produces an output voltage of 10 V rms across an 8 ohms load resistance. The power supply has a voltage of 15 V and delivers an average current of 2 A. Find the power dissipated in the amplifier and the efficiency of the amplifier. Select one: a. Pd = 10 W and Eff = 41.7% b. Pd = 30 W and Eff = 20% c. Pd = 17.5 W and Eff = 41.7% d. Pd = 17.5 W and Eff = 35.4% e. None of the answers
