Chris,
I wouldn't say that is being pedantic as it is a very important
point. The thickness of the wire has a very significant effect on the
amount resistance you will observe. At low voltage supply a 50W
output takes just over 4Amps if the voltage were 230v then you would
need just 0.2Amps. Hence why we distribute electricity at very high-
voltage in the Grid
