Brief LM334 three terminal adjustable constant current source

LM334s have a current that is set by an external resistor. That amount of current will flow through the LM334 and any series load/components as long as the power supply have a slightly higher voltage than the load needs.

Diagram

Video below demonstrates how to use the LM334 on a breadboard.
