WebNov 5, 2024 · The shunt resistor is a small resistor that “shunts” (deflects) the current away from the galvanometer, so that most of the current goes through the shunt resistor. This is illustrated in Figure \(\PageIndex{1}\), which shows the galvanometer (circle with the \(G\) inside), the internal resistance of the galvanometer, \(R_G\) , and the ... 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.
Conversion of Galvanometer into Ammeter: Experiment, Verification
WebApr 5, 2024 · S = shunt resistance. I g = nk is the needed full-scale deflection of a galvanometer. The unit of the figure of merit of a galvanometer is amp/div. I = A range of the desired ammeter in mA. The length of the wire required to create a shunt is calculated by: I = π\[^{r^{2}}\] S/ρ. Where, r = radius of the wire calculated by using a screw gauge. WebJan 25, 2024 · Working. The current entering the ammeter will be divided into two different parts according to \ ( {\rm {KCL}}\) in galvanometer and ammeter. Since the resistance of the shunt is very low, most of the current entering ammeter will pass through it, and a very less amount of current will pass through the galvanometer. dvostranački sustav
