A.)Engineers are tasked with calculating the dimensions of a transmission line from a power plant to a city 100 km away. The power plant outputs 765,000 V, and the transmission line must transport a minimum of 500,000 A of current. An intern looks up the value of resistivity from a database with the value of ?=1.29 ×10−8 Ω?. What is the diameter the wire the engineers need to use? Show work. B.) The intern was in the wrong database and...

Q1. You are given a 12 V DC power supply. You are expected to develop a voltage divider to achieve a voltage of nominal 5V value using a pair of resistors from the E 12 range, with the restrition that you are not expected to draw a current of more than 1 mA from the 12 V DC supply i. Develop a simple circuit showing the possible values for each resistor pair, and the range of the DC output possible...

Build an Op-Amp Circuit Network. Note you only have a power source of 5V available. You have a voltage signal that latches at a constant 1.5V. Create a difference circuit to produce an output voltage of 2V. Put P/Ns and element values in your design. Show your work. From part a)’s output voltage, assign that now as a reference voltage (Vref) to compare to an analog sensor signal (Vin) that can range between 0V – 5V. Make sure your circuit...
