A teacher in his physics laboratory allotted an experiment to determine the resistance $(G)$ of a galvanometer. Students took the observations for $\frac{1}{3}$ deflection in the galvanometer. Which of the below is true for measuring value of $G$ $?$
  • A$\frac{1}{3}$ deflection method cannot be used for determining the resistance of the galvanometer.
  • B$\frac{1}{3}$ deflection method can be used and in this case the $G$ equals to twice the value of shunt resistance$(s).$
  • C$\frac{1}{3}$ deflection method can be used and in this case, the $G$ equals to three times the value of shunt resistance$(s)$
  • D$\frac{1}{3}$ deflection method can be used and in this case the $G$ value equals to the shunt resistance$(s).$
