Dissociative Identity Disorder

Former Community Member

How does this forum protect itself against one lunatic with six different email addresses coming on and simply agreeing with himself all of the time?


One politician suffering with 'dissociative identity disorder' can theoretically vote for himself over and over again and really screw up a democratic system!


In old money; how do we guard against someone on here using "dead-men"?

    t is interesting to note that in devices like motors, transformers, etc., engineers sometimes use the term "back e.m.f." rather than "back voltage". Perhaps because this is rigourous analysis.


    I have been taught, that the EMF is what the voltage would be if no current were flowing, the "open circuit voltage"  if you will.


    The potential difference (PD) is however the voltage at the time of measurement, presumably on load.


    For things like 50ohm RF (or 75 ohm video) signals, it really matters, as the PD is then exaclty half the EMF when the load and source are properly matched for minimal reflection.

    regards Mike.
