I am building a power supply (16v 6.6a) and would like to monitor amperage output
I have tried using resistance wire on the ground side (return to supply),
Measuring voltage drop across it. This works but I don't think this is the best way to do it.
So I got a current sensing shunt resistor (.1ohm 5watt) its good for 15A
I like this but, my amperage reading on the digital meter is off by.05A
how do I adjust the circuit to compansate for the error. Or do I need a different value shunt resistor.
I am a newbie to electronics, Please help.
