What the 24VDC Power Supply Should Read

This is a simple lab. When students measure the 24VDC power supply, it should read around 24V. If it is higher or lower, it can be adjusted up and down with a screw driver. When the student swaps the multimeter leads, the voltage will go negative.

What They Should Learn

This shows that DC has polarity and that the current only flows in one direction.
