| In the given circuit the reading of voltmeter \[{{V}_{1}}\] and \[{{V}_{2}}\] are 300 V each. The reading to the voltmeter \[{{V}_{3}}\] and ammeter A are respectively [AIPMT (S) 2010] |
 |
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 :
| [b] 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 \[i=\frac{V}{R}=\frac{220}{100}=2.2A\] |
