Page 2 Problem 1 Print Your Name: _________________________________ Consider the circuit shown in the figure in which three resistors are powered by two batteries. a. (13) In terms of I 1 , I 2 , I 3 , R 1 , R 2 , R 3 , ε A , and ε B , write Kirchoff’s Junction Rule for point (e), Kirchoff’s Loop Rule for the loop (abefa), and Kirchoff’s Loop Rule for the loop (bcdeb). The solutions to the equations in Part a are: I 1 = 0.20 A, I 2 = 0.20 A, and I 3 = 0.40 A (with directions shown in the figure). Use these values to calculate the following.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
