Could you please answer these questions and show all steps
Problem 5 (20 points) Consider the following circuit 2V 12V a) How many nodes do we have in this circuit? Verify KVL b) How many distinct voltages do we have? List them using the double subscript notation, for example Vab. Do not list the negative of the same voltage; for example if you list Vab do not list a c Which ones of these distinct voltages are not given directly? d) Calculate these voltages using KVL
Problem 3 (20 points) Consider the following circuit a) Write the formulas that can be used to calculate power absorbed by a resistor b) Assume we know that V-12 V and R-10 k2. Calculate the current I. Calculate power absorbed by the resistor using three alternative formulas c) Assume we know that Vs-12 V and the current /is 0.6 A. Calculate the resistance R Calculate power absorbed by the resistor. Calculate power supplied by the source. Verify Tellegens theorem. d) Assume we know that R-1002 and the current /is 1A. Calculate the power supplied by the source without calculating the voltage V Problem 4 (20 points) Consider the following circuit Rs R2 How many currents do we have at node 2? What law can we apply at node 2 to calculate one unknown current? Do we need to apply that law at node 3? Can we apply the same law at node 4 as we do at node 2? a) b) Assume we know that /-3mA and h-ImA. Calculate the current Is. What is the current c) Assume we know that that I2-3 mA and -ImA. Calculate the current . What is the d) Assume we know that /1-3 mA and 1 1mA. Calculate the current /2. through the resistor R4? current through the voltage source?
