Step 1 of 2 1.011E Calculate the DC power. = Substitute 15 for V and = Calculate the power delivered to the load. = R Substitute for Vₘₐₓ and for Step 2 of 2 Calculate the power dissipated in the amplifier. Substitute 18 mW for and 120 mW for Therefore, the power dissipated in the amplifier, Pdissipated is 102 mW Calculate the efficiency. Substitute 18 mW for and 120 mW for =15% Therefore, the efficiency of an amplifier, n is 15%
