Step 1 of 3 2.003E Refer to Figure1 11.2 in the textbook. (a) Calculate the average power delivered to the load, = 2 Substitute 8V for and 100 Ω Ω for 100 Therefore, the power delivered to the load, is Step 2 of 3 (b) Calculate the average power drawn from the supplies, Substitute 10 V for and mA for = =(20)(0.1) =2W Therefore, power drawn from the supplies, is 2W Step 3 of 3 (c) Calculate the power conversion efficiency, Substitute 0.32 W for and 2 W for = 16% Therefore, the power conversion efficiency, n is 16%
