Prob 8-32 Fig 8-87 Write the mesh equations; solve for the loop currents. @I1: -I1R1–I1R2 + I2R2 +9 = 0 => -I1*2 – I1*3 +I2*3+9 = 0 => -I1(2+3) +I2*3 =- 9 => I1(-5) +I2(3) + I3(0)= -9 @I2: -I2R2 + I1R2 – I2R3 -6 = 0 => -I2*3 + I1*3 – I2*4 – 6 = 0 => I1(3)–I2(3 + 4) - 6 => I1(3)+I2(-7)+I3(0) = 6

    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.
