Calculating voltage using Kirchhoff loops 0 solutions submitted (max: Unlimited) This example demonstrates assessing correctness by checking the value of variables in the student solution. The student must show physical understanding of a system to correctly setup and solve the problem. Assessment of intermediate variables is used to provide feedback on each step in the student solution. Kirchhoffs laws are widely used in electrical engineering to find currents or voltages in closed circuits. Ohm's Law(V system of linear equations that can then be soved using linear algobra. For example, IR) is used to write equations representing each loop in the circuit. As was discussed in class, these equations can be used to builda For this problem, you have been provided the c cult show below bel Use Kr h loops lo create a system of equations. A range your e a ns so that the vol ages are all positive o ve for the current 1 using the current op directions defined for and 62 1 2 9V 1012 1.5V Your solution should 1. Create a variable named V that contains the voltage (in Volts) for loop I, in the first row, loop I, in the second, and loop e in the thired. 2. Create a variable named R that contains the equation coefficients (in Ohms). Place coefficients for current Ia in the first column, I, in the second, and Ie in the third. Place the equation for loop I on the first row, 1, on the second, and e on the third 3. Solve the set of linear equations for current (in Amps) and store the result in a variable named I 4, Calculate the voltage drop across the 8 resistor between nodes c and f using Ohm's Law and the loop currents solved for previously.
