Measuring the latter allows a constant power load mode (as power = current * voltage). In his article, [Kerry] shows that he can simulate a load of up to 200W.

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 ...

In GPS and wireless communication, a constant voltage is vital at a desired network branch. But how to achieve that? One can ...
