A) \[7.2\,\times {{10}^{3}}J\]
B) \[14.4\,\times {{10}^{5}}J\]
C) \[43.2\,\times {{10}^{4}}J\]
D) \[28.8\,\times {{10}^{4}}J\]
Correct Answer: B
Solution :
Given,\[R=6\Omega ,\,\,t=10\min =600s\] \[V=120\,\,volt\] Energy liberated\[=\frac{{{V}^{2}}}{R}\cdot t\] \[=\frac{120\times 120\times 600}{6}\] \[=144\times {{10}^{4}}J\] \[=14.4\times {{10}^{5}}J\]
