I - Prelab: 1- To get R TH , we short circuit all the voltages sources and then we calculate the equivalent resistance: 2 R (| | 2 R ) + R ¿ )∨ | 2 R ) + R = R ¿ Rth = ¿ To solve this circuit, we need to use the superposition theorem (leave one of the 3 voltages sources and short the other 2). Using voltage divider method we calculate V 0 Short V 2 and V 3 , Leave V 1 : V Th1 = V 1 = V TH1 =2R*V 1 / (2R+2R) =V1/2 R R R R R R R 2 ) ) 2 // ) ) 2 // 2 (((( 2 1 4 2 V R R

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.
