A) low resistance shunt in series
B) low resistance shunt in parallel
C) high resistance shunt in series
D) high resistance shunt in parallel
Correct Answer: B
Solution :
Key Idea: An ammeter has low resistance in the circuit as it measures the strong current. A galvanometer as such cannot be used as an ammeter because it has appreciable resistance and it can measure only a limited current corresponding to the maximum deflection on its scale. In practice, an ammeter is made by connecting a low resistance S in parallel with a pivoted type moving coil galvanometer G. S is known as shunt. Its Value depends upon the range of the required ammeter.You need to login to perform this action.
