In this electronics basics episode we will be having a look at negative DC voltages. Now you usually do not require them alone, but pretty much always with a positive voltage as well. In this case the power supply that can provide these two voltages is called a dual rail power supply. So in this video you will not only find out where you need such a dual rail voltage but also how to create one with 3 different techniques! Let's get started!
