A) \[1:1\]
B) \[1:4\]
C) \[2:1\]
D) \[1:2\]
Correct Answer: D
Solution :
In series combination, power dissipated, \[\Rightarrow \,\,\,\,P\propto {{l}^{2}}R\] \[\Rightarrow \,\,\,\,\,P\propto R\,\,\,\,\,or\,\,\,\,\,\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{{{R}_{1}}}{{{R}_{2}}}\] Here \[{{R}_{1}}:{{R}_{2}}=1\,\,:\,\,2\] \[\Rightarrow \,\,\,\,\,\,\,\,\,\frac{{{P}_{1}}}{{{P}_{2}}}=\frac{1}{2}\,\,\,\,\Rightarrow \,\,\,{{P}_{1}}:{{P}_{2}}\,\,=1\,\,:\,\,2\]You need to login to perform this action.
