A) \[\frac{1}{4}\]amp
B) 4 amp
C) \[\frac{1}{2}\]amp
D) 2 amp
Correct Answer: A
Solution :
\[P=\frac{{{V}^{2}}}{R}\Rightarrow 100=\frac{{{(200)}^{2}}}{R}\] Þ \[R=\frac{4\times {{10}^{4}}}{{{10}^{2}}}=400\,\Omega \] Now, \[i=\frac{V}{R}=\frac{100}{400}=\frac{1}{4}amp\]You need to login to perform this action.
