A) V=100 volt, I = 2 amp
B) V = 100 volt, I = 5
C) V = 1000 volt, I =2 amp
D) V = 300 volt, I = 1 amp
Correct Answer: A
Solution :
Here, \[{{V}_{L}}={{V}_{C}}.\] they are in opposite phase. Hence, 'they will cancel each other. Now, resultant potential difference = applied potential difference \[=100\,V.\] \[z=R,\]\[\therefore \]\[{{I}_{rms}}=\frac{{{V}_{rms}}}{z}\frac{{{V}_{rms}}}{R}=\frac{100}{50}=2\,\text{Amp}\text{.}\] Hence, the correction option is [a].
