RESULTS/ANALYSIS: Part 1: What dc voltage does the circuit generate? V V DC 5 . 8 = What is the ripple? mV V rippple 3 = Part 2: What are the dc voltages and ripples of the two sections? Apart from the negative polarity, is there any other difference between the two output voltages? V V DC 10 1 - = V V DC 10 2 = V V ripple 5 . 1 = V V rippple 45 . 2 = No there is no difference between the two output voltages besides polarity. Part 3: What is the dc voltage and ripple of this supply? How would you make negative polarity voltage doublers? V V DC 9 = V V ripple 75 . = How would you make negative polarity doublers?

### 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.
