A) \[\frac{{{R}_{2}}}{{{R}_{1}}}\]
B) \[\frac{{{R}_{1}}}{{{R}_{2}}}\]
C) \[\frac{R_{1}^{2}}{R_{2}^{2}}\]
D) \[\frac{R_{2}^{2}}{R_{1}^{2}}\]
Correct Answer: A
Solution :
Heat produced \[H=\frac{{{V}^{2}}t}{4.2R}=H\propto \frac{1}{R}\] Hence \[\frac{{{H}_{1}}}{{{H}_{2}}}=\frac{{{R}_{2}}}{{{R}_{1}}}\]You need to login to perform this action.
