but as i explained, the amperage is the result (product) of voltage and resistor (also very very basic > Ohm's Law).
the serial resistor is given by the human body itself, the electric condutance of his piss as well as body to earth condutance. that's the way where the current will flow throu, after his urin once meets the main supply of the PS2.
therefore:
-Serial Resistor = fix given (unaltered)
-Voltage = variable
-Current = depends on the Voltage
example 1 (would happen in the US): serial resistor R = 10K, Voltage U = 110V
I = U/R = 0.011Ampere
example 2 (would happen in the europ): serial resistor R = 10K, Voltage U = 230V
I = U/R = 0.023Ampere
so which hurts the more?
