Options

  1. A

    13\frac{1}{3}31​ deflection method cannot be used for determining the resistance of the galvanometer.

  2. B

    13\frac{1}{3}31​ deflection method can be used and in this case the GGG equals to twice the value of shunt resistance(s).

  3. C

    13\frac{1}{3}31​ deflection method can be used and in this case, the G equals to three times the value of shunt resistance(s).

  4. D

    13\frac{1}{3}31​ deflection method can be used and in this case the GGG value equals to the shunt resistance(s)
