audioguru Posted March 13, 2006 Report Share Posted March 13, 2006 my voltmeter has range of 0-30VDC and a full scale current of 27.5mA.what is the value of series resistor should i put to convert it into an ammeter with 0-3A range..?Most digital meters have a 200mV full-scale and an extremely low input current.Most moving coil meters are also very sensitive.If resistors can't be removed from your meter to make it more sensitive then a complicated amplifier is needed for it.
