    In the given circuit the reading of voltmeter \[{{\text{V}}_{1}}\]and \[{{\text{V}}_{\text{2}}}\] are 300 V each. The reading to the voltmeter \[{{\text{V}}_{3}}\] and ammeter A are respectively

    A) 150 V, 2.2 A                        

    B) 220 V, 2.2 A

    C) 220 V, 2.0 A        

    D)        100 V, 2.0 A

    Correct Answer: B

    Solution :

    For series LCR circuit voltage \[V=\sqrt{V_{R}^{2}+{{({{V}_{L}}-{{V}_{C}})}^{2}}}\] Since, \[{{V}_{L}}={{V}_{C}}\]hence\[V={{V}_{R}}=220\,V\] also, current \[i=\frac{V}{R}=\frac{220}{100}=2.2A\]
