Question 289: Current Electricity

Question

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:

Accepted Answer

According to the information, current through galvanometer = nK
$$ \Rightarrow {S \over {S + G}}i = nK$$
$$ \Rightarrow i = {{nK(S + G)} \over S}$$

Answer

$${{KS} \over {(S + G)}}$$

Answer

$${{(G + S)} \over {nKS}}$$

Answer

$${{nKS} \over {(G + S)}}$$

Answer

$${{nK(G + S)} \over S}$$
