Galvanometer shunt resistance formula
WebWhat is the formula of shunt resistance? Shunt resistors have a maximum current rating. The resistance value is given by the voltage drop at the maximum current rating. For example, a shunt resistor rated with 100 A and 50 mV has a resistance of 50 / 100 = 0.5 mΩ. ... The full-scale current is known to be 1.0 mA, but the galvanometer ... WebA galvanometer has a resistance of 99 Ω. It is shunted with 1 Ω resistance. The ratio of the currents flowing through the galvanometer and through the shunt is-

WebA galvanometer has a resistance of 12 mΩ. A current of 150 mA produces full-scale deflection of the galvanometer. A shunt is connected in parallel with the galvanometer to convert it into an ammeter. The resistance of the shunt is 70 µΩ. Web1. Shunt: A shunt is a low resistance usually used to convert a galvanometer to an ammeter. It is usually connected in parallel with the galvanometer. I – Current to be measured. I g – Current through the …
WebSince the shunt resistance is small, most of the current passes through it, allowing an ammeter to measure currents much greater than those producing a full-scale deflection of the galvanometer. Suppose, for example, an ammeter is needed that gives a full-scale deflection for 1.0 A, and contains the same 2 5- Ω 2 5- Ω galvanometer with its 50 ...
WebShunt resistance Since galvanometer is a very sensitive instrument therefore it can't measure heavy currents. In order to convert a galvanometer into an ammeter, a very …
