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, \[R=6\Omega ,\] \[t=10\min =600s\] \[V=120volt\] Energy liberated \[=\frac{{{V}^{2}}}{R}.t\] \[=\frac{120\times 120\times 600}{6}\] \[=144\times {{10}^{4}}J\]You need to login to perform this action.
