A) \[2:1\]
B) \[1:2\]
C) \[2:9\]
D) \[9:2\]
Correct Answer: C
Solution :
In series, \[{{R}_{S}}=R+2R=3R\] In parallel,\[{{R}_{p}}=\frac{R\times 2R}{R+2R}\] \[=\frac{2{{R}^{2}}}{3R}\] \[=\frac{2}{3}R\] Ratio of heat produced \[\frac{{{H}_{s}}}{{{H}_{p}}}=\frac{{{R}_{p}}}{{{R}_{s}}}\] \[=\frac{\frac{2}{3}R}{3R}=\frac{2}{9}\] \[{{H}_{s}}:{{H}_{p}}=2:9\]You need to login to perform this action.
