How inefficient are resistors?
Does this mean higher resistance is less lossy and by definition, more efficient, or is this simply due to the fact that there is less current flow, and less power loss, and efficiency (% of power loss)
With an ideal constant current source, will the losses though any resistive load be equal? ( X amount of watts lost/dissipated @ 1A)
Is it possible to limit current like a resistor without losses? (I know PWM techniques are more efficient, but I want actual resistance rather than chopping current flow and filtering with an inductor/capacitor RC filter)
