Galvanometer shunt resistance formula
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 … 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 ...

Webthe value of shunt resistance S, the deflection of the galvanometer needle becomes 1 2 (half). As G and S are in parallel combination and R in series with it, the total resistance … 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.
WebSolving for the shunt resistance: 4 æ Û L 4 à + à : Ù æ ; + F + à : Ù æ ; L 4 à + + à : Ù æ ; 1 This equation is the ammeter equation, which provides the necessary shunt resistance for a meter of range I. The full-scale current is known to be 1.0 mA, but the galvanometer resistance must be measured. WebThe instrument, which is used to measure the Direct Current called DC ammeter. If we place a resistor in parallel with the Permanent Magnet Moving Coil (PMMC) galvanometer, then the entire combination acts as DC ammeter. The parallel resistance, which is used in DC ammeter is also called shunt resistance or simply, shunt.
