A) 120 V, 3 A
B) 120 V, 6 A
C) 0 V, 8 A
D) 0 V, 3 A
Correct Answer: C
Solution :
As,\[{{X}_{L}}={{X}_{C}}\], so \[{{V}_{L}}\,\,and\,\,{{V}_{C}}\] are equal and opposite phase i.e., voltmeter reading will be zero. Also \[R=30\,\Omega ,\,\,{{X}_{L}}={{X}_{C}}=25\,\Omega \] \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,\,\,i=\,\,\frac{V}{\sqrt{{{R}^{2}}+{{({{X}_{L}}-{{X}_{C}})}^{2}}}}\] \[=\,\,\,\,\frac{V}{R}=\frac{240}{30}=8\,A\]
