A) \[\frac{L{{E}^{2}}}{6{{R}^{2}}}\]
B) \[\frac{L{{E}^{2}}}{4{{R}^{2}}}\]
C) \[\frac{4{{R}^{2}}}{L{{E}^{2}}}\]
D) \[\frac{L{{E}^{2}}}{{{R}^{2}}}\]
Correct Answer: B
Solution :
[b] Max. energy stored in \[2L\] inductance \[U=\frac{1}{2}.2L{{\left( \frac{E}{2R} \right)}^{2}}=\frac{L{{E}^{2}}}{4{{R}^{2}}}\] This stored magnetic energy is completely converted into heat.You need to login to perform this action.
