A GALVANOMETER HAS LOW RESISTANCE AND HENCE LARGE CURRENT FLOWS THROUGH IT.DUE TO THIS CURRENT AND THE POTENTIAL DIFFERENCE ACROSS A CONDUCTOR DECREASES.HENCE,THE GIVEN GALVANOMETER CANNOT BE USED TO MEASURE THE POTENTIAL DIFFERENCE ACROSS A CONDUCTOR.BUT WE CAN CONVERT A GALVANOMETER INTO A VOLTMETER.
