# Bench Power Supply Basics | Workbench Wednesdays


A bench power supply makes powering circuits easy and safe. Learn how to adjust basic controls like voltage. Finally, see how "current limiting" works (and why you should use it.) See how you can use built-in series or parallel tracking to increase a bench power supply's voltage or current output. Last, if you are in the market for a power supply, do not forget to add some leads like mini-grabbers, alligator clips, and banana plugs.
