Arial, sans-serif;text-align:justify;">A bench power supply makes powering circuits easy and safe. Learn how to adjust basic controls like voltage. Finally, see how &quot;current limiting&quot; works (and why you should use it.) See how you can use built-in series or parallel tracking to increase a bench power supply&#39;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.</span></p> <p style="margin:0;padding:0px;">&nbsp;</p> <p
