1. A. Hoover dam is located 275 miles from Los Angeles and it supplies 60 Hz power to the city. Can electric circuit theory be used to analyze this circuit or not? Show all calculations and explain the reasoning behind your answer. B. Explain why circuit theory might be preferred over the more general electromagnetic theory when solving practical problems as in A above. 2. Voltage, current, and power are the primary parameters utilized in electric circuits. Define each of these three parameters with equations and identify all the terms in these equations and give the units of each term. Note that Ohm's Law is not involved in these defining equations. 3. Write equations for Ohm's law and for Kirchoff's laws. Use these laws to find the current in the voltage source in the circuit below, I, and find the voltage on the 7 ohm resistor. Show all your calculations. 55 9V (+) 8V( 3n www 4. Find v₁ and v₂ in the circuit below. Show all your calculations. 355 12V 652 200 V₁ 20k 2105 10K m 20 €3,000 50k 12052 5. Design a voltage divider circuit with 4 output voltages equal to 4V, 2V, V, and 0.5V when referred to one common terminal if the voltage source is a 6 V battery 32 6. A. Design a 10V full scale voltmeter using a d'Arsonval meter movement with 100 microampere full scale deflection and 100 ohms of coil resistance. B. What voltage will this meter read when connected in the circuit as shown below? 752 100 + V₂38052 voltmeter

please answer the following in the image

2 parts ( A-B ) Read and solve carefully please write clearly and box the final answer Part A - What is the value of the resistor shown below in ohms? Don't use scientific notation.? Part B - What is the numerical value for LED_BUILTIN for Arduino Uno? In other words, which pin is connected to the built-in LED?

can you do question iii please?
