A) \[\frac{{{S}^{2}}}{(S+G)}\]
B) \[\frac{SG}{(S+G)}\]
C) \[\frac{{{G}^{2}}}{(S+G)}\]
D) \[\frac{G}{(S+G)}\]
Correct Answer: C
Solution :
Current will be unchanged if resistance remains same so \[G=\frac{GS}{G+S}+R\] \[R=G-\frac{GS}{G+S}\] \[R=\frac{{{G}^{2}}}{G+S}\]You need to login to perform this action.
