A) \[~0\text{ }V,3\text{ }A\]
B) \[150\,V,3A\]
C) \[150\,V,6A\]
D) \[0\,V,8A\]
Correct Answer: D
Solution :
The voltage\[{{V}_{L}}\]and \[{{V}_{C}}\]are equal and opposite and voltmeter reading will be zero. In the circuit\[~R=30\text{ }\Omega \] In the circuit\[{{X}_{L}}=25\,\Omega \] In the circuit \[{{X}_{C}}\text{ }=25\,\Omega \] In the circuit A.C. voltage and frequency = 240 volt, 50 Hz (Given) The value of \[i\] is given by from the relation \[i=\frac{V}{\sqrt{{{F}^{2}}+{{({{X}_{L}}+{{X}_{C}})}^{2}}}}=\frac{V}{R}=\frac{240}{30}=8\,\text{amp}\text{.}\]
