    Convert 120v AC to -5v DC

    I have a device that runs on -5v DC but I only have 120V AC. I need to build a power supply that can convert 120v AC to -5v DC. I need to draw the best power supple and indicate the wave form at each stage.

    Purpose of a rectifier in a positive oscillating circuit

    Hello, I found a circuit (transmitter) design that would create an oscillating magnetic field. Another circuit (receiver) would pick the induced voltage up and amplify it. Now as I understand it, the oscillating part has only positive voltage. But in the receiver part they use a recitfier. Why...

    5V Adapter

    Hello guys, how are you all doing? During the past few months I've been going through the Textbooks AAC has published, experimenting with some minor circuits and even PIC microcontrollers. I've learned a lot during the process and decided to do something a bit more challenging - make a basic...
