2. The output voltage of a three-terminal voltage regulator is 3.3 V at 5 mA Joad, and 3.25 V at 3 A load. Calculate the output resistanc ce of the regulator. (15%)

6. An amplifier is designed to provide a 12 V peak-to-peak swing output at no load condition. Assume the input signal is sinusoidal. The amplifier has output resistance Ro=0.4Ω. A load =4Ω is connected to the output of the amplifier, how much power will dissinate? (20%)
