Hello all,
I found this article and i was wondering if someone could explain a little bit better.
http://lygte-info.dk/info/How do I test a charger UK.html
Are the resistors effectively in parallel with the shunt resistor inside the dmm, is that how this works? If i am thinking correctly when you measure the current you could draw a current source in parallel with the network of .1 ohm resistors, but how does that "cancel" the lead resistance? Does it have to do with the voltage drop caused by the network of .1 ohm resistors somehow making up for the voltage drop in the leads?
