How to calculate shunt voltage for the current register calculations

current register = shunt voltage * calibration register / 4096

  • Hello, 

    To calculate shunt voltage you will need to multiply the Rshunt by the Current through the shunt. (Vshunt = Rshunt * Current)

    So if I am using a .01 Ohm resistor and expect a current of 2 A my shunt voltage will be Vshunt = .01*2 = .02 V or 20 mV.
