use these two images to answer all these questions: What are the differences between ac and dc meters? Can you compare the value of the current in the load resistance for the same value of voltage with ac and dc supply? What is the function of the autotransformer in this circuit? Can you use an autotransformer to obtain variable output voltage from a fixed dc supply? What will happen if dc meters are used instead of ac meters in this circuit? What the difference between resistance and impedance is when referred to dc and ac measurements?

Question 3: A very simple model for the distribution of clectricity to a typical home is shown in the figure below. Some of components labeled a, b, c, d, c, f, g and h represent the electrical source to the home, some represent the wires that carry the electrical current from the source to the devices in the home requiring electrical power, some represent lamps, televisions, hair dryers and other devices that require power. Assume you are an engineer in charge of a project and one of your subordinate engineers reports that the interconnection in the figure does not pass the power check. The data for the interconnection are given in the table below. Is the subordinate correer? Explain your answer. If the subordinate is correct, find the error in the data. Explain your answer clearly.

Which of the following statements are correct for the circuit below? Thanks to the capacitors I – C1 and C2, the voltage gain of the circuit increases. II – Capacitors C1 and C2 are coupling capacitors and provide an isolation function between AC and DC voltages in the circuit. Thanks to the III – RE resistor, the voltage gain of the circuit increases. Thanks to the IV – RE resistor, the stability of the circuit increases. The V – C3 Capacitor is a bypass capacitor and prevents the loss of voltage gain. Capacitor VI – C3 is a coupling capacitor and has no effect on the voltage gain in the circuit. VII – As the value of the source internal resistance Rs increases, the voltage gain decreases. VIII – The voltage gain decreases as the value of any RL load to be added to the circuit increases

PROBLEM #1 A 7-segment display is a common display device having 7 light segments that can be lit in different patterns to represent numbers and some letters. Each segment is assigned to a particular label: a, b, c, d, e, f, or g (as shown in figure to the right). To display a particular number or letter, each of these segments is either "on" or "off". Assume a "1" turns 'on' the corresponding segment and a "0" turns 'off' the corresponding segment. Problem description: You, as part of a team, have been hired by ACME University to design a display that reminds the departmental staff of the fiscal year by displaying the semester name and the last two digits of year. This semester, the message should read "FL2024" using 7- segment displays. Since only certain letters and numbers are relevant, the design team has decided to use a 3-bit CODE for each of the distinct characters needed for the SPR24 message. The encoding shown in the figure below. (Specifically, "000" will be used to…
