## Main Question or Discussion Point

Couldn't we just say the voltage could be variable, hold that as a constant, and design circuits which could run off completely safe 12v systems? Why not use fractional resistors to get the amperage to an arbitrary value?

In other words could you just make a resistor valued at, say, 0.10 ohms, to generate the same amperage as a 1 ohm system running at 10 times the voltage? So why even play with higher voltages?
