I - Prelab: 1- To get R TH , we short circuit all the voltages sources and then we calculate the equivalent resistance (((2R//2R + R) // 2R) + R) // 2R = R = R TH To get V TH , we use the superposition method: short circuit each 2 voltages sources, keep the third one. Using voltage divider method we calculate V 0 Short V 2 and V 3 , Leave V 1 : V TH1 = V 0 =2R*V 1 / (2R+2R) =V1/2 Short V 1 and V 3 , Leave V 2 : V TH2 =V 0 = 2R*V 2 / (2(2R+2R)) =V

### 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.
