Experiment 6 – DC Power Supplies Introduction: The purpose of this lab report is to inform the lab assistant that I’ve worked through the lab and gained an adequate amount of experience in doing so. The information in this lab deals with constructing unregulated power supplies. Objective: The main objective of this lab is to apply the ideas used in experiment 5 to build practical power supplies that are unregulated. Procedure: First, we make a circuit by connecting a 6-volt RMS transformer, two 330µF capacitors, a diode, a 1kΩ resistor, and an inductor. One capacitor in series with the diode. Attached in between the first capacitor and the diode is the inductor with the second capacitor connected on the other end paralleled with the 1kΩ resistor. The 6-volt RMS is connected between the diode and the first capacitor. When connecting the circuit, we made sure the power to the breadboard was turned off. We next connect the circuit to the oscilloscope and measure its DC voltage as well as ripple voltage. Secondly, we make a circuit by connecting both 330µF capacitors and two diodes in series. Arranged diode, capacitors, and then diode. We then connect two 1kΩ resistors and parallel them to the capacitors; one per capacitor. The 6-volt RMS transformer is connected in between both capacitors as well as to the p-side of one diode and to the n- side of the other. The transformer is also grounded where the wire connects it to the

    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.
