P1. [Power Semiconductor Devices] The design challenge at hand involves the task of generating a stable DC voltage from a 9-V battery source. The goal is to provide a 3-V output to power a load resistance represented as $R_L$. There are two potential approaches, as shown in Fig. 1, to achieve this: one is to employ a voltage divider circuit using a resistor twice the value of $R_L$, and the other is to use a switched circuit. [A] In the voltage divider circuit, sketch the output voltage across the load resistance $R_L$ and compute the losses in $2R_L$. [B] In the switched circuit, determine how frequently the switch needs to toggle on and off to maintain a 3 V output at the load side ($R_L$). Sketch the output voltage $v_z(t)$. [C] What is the power absorbed by the switch for both open and closed conditions? [D] Which circuit is likely more efficient in terms of the power consumed by the element used to regulate the voltage? Hint: Compare the results in part (C) with the losses computed in part [A]. [E] Why is it necessary to use a low-pass filter on the load side in the case of switched circuit? Hint: Compare the output voltage waveform in part [A] and [B]. [F] Repeat part [B] considering the 9-V battery decreased to 6 V. Would the switch need to turn on for a longer duration to maintain the 3 V output on the load side?

49. If two sides and the angle opposite one of them in a triangle are equal to the corresponding parts of another triangle, then it follows that the triangles are congruent. A. This statement could never be true. B. This statement is always true. C. This statement could be true if the hypotenuse and a leg of one right triangle are equal to the corresponding part of another right triangle. D. This statement could be true if the corresponding angles are right angles. 50. In the figure below, $\triangle QRS$ is the reflection of $\triangle XYZ$ through line $m_1$, and $\triangle LMO$ is the reflection of $\triangle QRS$ through $m_2$. Line $m_1$ is parallel to line $m_2$. Through what transformation is $\triangle LMO$ the image of $\triangle XYZ$? A. a translation B. a reflection C. a rotation D. a translation and a rotation
