A) \[\frac{1}{4}\] amp
B) 4 amp
C) \[\frac{1}{2}\] amp
D) 2 amp
Correct Answer: A
Solution :
Here: P = 100 watt, V = 200 V From the formula \[P=\frac{{{V}^{2}}}{R}\] So \[R=\frac{{{V}^{2}}}{P}=\frac{{{(200)}^{2}}}{100}\] again \[i=\frac{V}{R}=\frac{100}{{{(200)}^{2}}}\times 100\] \[(\because \,V=100\,V)\] \[=\frac{1}{4}\,amp\]
