Hi All,
I have been trying to mae a circuit which i could use to measure the current accross a shunt . I md a circuit using an lm3914, but i a not having any luck,the lm3914 is powered by the transformer of the unit i am testing(regulated and rectified),if my positive and negative come from the transformer , i take one pin to one side of the shunt,should i have an opamp going to both sides of shunt and then to the lm3914,anyb help would be appreciated ,as i am at a dead end.
