Current Electricity question

2022 · 25 Jun · Shift 2 · Q63

JEE MainPhysicsCurrent ElectricityMCQ+4 / −1
If n represents the actual number of deflections in a converted galvanometer of resistance G and shunt resistance S. Then the total current I when its figure of merit is K will be:
  1. A
    KS(S+G){{KS} \over {(S + G)}}(S+G)KS​
  2. B
    (G+S)nKS{{(G + S)} \over {nKS}}nKS(G+S)​
  3. C
    nKS(G+S){{nKS} \over {(G + S)}}(G+S)nKS​
  4. D
    nK(G+S)S{{nK(G + S)} \over S}SnK(G+S)​
