| DC power supplies typically have multiple outputs. Based on the needs of your device, you will need to choose an appropriate output that supplies enough voltage and current. It is ok if the output is rated for a higher voltage/current than your device needs, but you will run into problems if the output voltage/current is less than the demands of your device. | | DC power supplies typically have multiple outputs.

− | Once you have selected your output, connect wire leads to your breadboard or device using the banana plugs or alligator clips. You can also connect 22 AWG wire directly to the terminal if you unscrew the banana plug terminal, insert a section of bare wire, and screw the terminal back down to create a solid connection. However, use banana plugs or alligator clips first to avoid wasting wire. If you are using additional instruments on the workbench such as the oscilloscope, signal generator, multimeter, or another power supply, you should create a common ground between all instruments to ensure that you get accurate measurements, don’t have weird floating ground points, and don’t have other strange circuit operation. After you’ve checked all of your connections, it would be a good time to discuss a few safety notes before turning everything on. | + | Once you have selected your output, connect wire leads to your breadboard or device using the banana plugs or alligator clips.
