Investigating potential power current sources capable of handling both AC and DC currents using the LM317 current source.

In his video [Afroman] describes how the LM317 can be used to regulate current rather than voltage to provide a constant current source under ... While this circuit may not be as efficient as ...

[YS] was inspired to come up with the circuit after reading Wednesday’s Re:load dummy load post. That was a constant current load, not a constant resistance load. [YS] started with the schematic ...
