[NSRCA-discussion] Max volts

[Ed Alt]

Yeah, it's the change in the current in the primary winding that cause a change in the magnetic flux density.  As that happens, a voltage is induced in the secondary winding due to the wire in that winding cutting through the varying lines of magnetic force as they collapse (in Bill's example). Works the same whether it's increasing or decreasing, just the polarity of the induced voltage varies.  There's more to it than that, but that's the general idea.

Seems to me I recall an ignition coil works on DC--but it doesn't work until the primary circuit is broken, I believe.

  I once was told that DC wouldn't go through a transformer so I got a 100:1 transformer and told the person to "hold these wires" and then connected a battery to it.

  His mind is still messed up...

        But everyone knows it is current, not voltage, that kills. :-)



        (I am just joking, BTW.)

          Biggest problem with raising the voltage is that 40v is generally considered the max non lethal voltage.    You'll be hard pressed to get a voltage increase for general safety reasons. 

          I'm sure that's why the current limitation  is in the general guidelines in the first place.
