You may hear the buses referred to by different names for example, power bus, positive bus, and voltage bus all refer to the one next to the red line with the plus (+) sign. They are called the buses, also referred to as rails, and are typically used to supply electrical power to your circuit when you connect them to a battery pack or other external power supply. These strips are typically marked by red and blue (or red and black) lines, with plus (+) and minus (-) signs, respectively. To learn more about individual electronic components, see our These holes let you easily insert electronic components to prototype (meaning to build and test an early version of) an electronic circuit, like this one with a battery, switch, resistor, and an LED (light-emitting diode).
