A) \[\text{3}.\text{3}\times \text{l}{{0}^{\text{5}}}\text{J}\]
B) \[2.5\times {{10}^{3}}J\]
C) \[1.5\times {{10}^{2}}J\]
D) \[{{10}^{8}}J\]
Correct Answer: A
Solution :
From Joules law, the energy dissipated is \[E={{I}^{2}}Rt\] Given, \[I=5A,\,\,\,R=44\,\,\Omega \], \[t=5\,\min =5\times 60\] \[\therefore \] \[E=3.3\times {{10}^{5}}J\]You need to login to perform this action.
