WebA galvanometer can act as a voltmeter as long as we pass a very minimum voltage like 1mv. This is because: A galvanometer has a specific resistance RG. When we pass some current I, the pointer in the galvanometer will deflect. Now, voltage V can be calculated by the formula: V= IRG. Web31 de dez. de 2013 · As the galvanometer's resistance (100 Ohms) is much much greater than the shunt resistance (10 mOhm), we can pretty much disregard the effect of paralleling the galvanometer's coil to our shunt. Thus, in effect the Ammeter we have created, has 10 milliOhms of resistance, which is pretty much negligible, and reads up to 1 Ampere current.
