A) 30\[\sqrt{2}\]A
B) 60 A
C) 100 A
D) 60\[\sqrt{2}\]A
Correct Answer: B
Solution :
The impedance of the circuit is \[Z=\sqrt{{{R}^{2}}+{{({{Z}_{L}}-{{X}_{C}})}^{2}}}\] \[{{X}_{L}}=\omega L=400\times 20\times {{10}^{-3}}=8H\] \[{{X}_{C}}=\frac{1}{\omega C}=\frac{1}{400\times 625\times {{10}^{-6}}}=4C\] \[Z=\sqrt{{{(3)}^{2}}+{{(8-4)}^{2}}}=5\] \[i=\frac{E}{Z}=\frac{300}{5}=60A\]You need to login to perform this action.
