You were tasked with modifying an audio amplifier circuit. Amplifier circuits are responsible for increasing the current sent to the speakers, avoiding damaging the sound device. The original design is shown in the figure. You want to increase the current I1 by a factor of 10 (10 times). The conditions of the design area are: Both font values ​​must be increased. None of the values ​​can be equal to 0. What are the new values ​​that you propose for the design of the amplifier? ** Argue your answer by analyzing the results obtained through calculations. (Check image 4 for the circuit)

Answer for #'s 4 and 5 please.

Often it is useful to model complex chips as simple linear equivalent models to determine the effects of the current draw and to ensure safe operation of the circuit. Consider the circuit shown in figure 5, it is a model of a digital microprocessor circuit. Each current source represent the current drawn by a portion of a digital circuits in the microprocessor. The resistors represent the power distribution network from the supply to that portion of the processor. Each current source can only have the following values: either be off i.e. 0 or have a value of I.. The reason being digital circuits when they are not performing a computation consume zero power and when operational they consume an average current (in this case I). In our model all portions consume the same current when they are operational.
