Alternating Current - Result Question 22
22. In the given circuit the reading of voltmeter $V_1$ and $V_2$ are 300 volts each. The reading of the voltmeter $V_3$ and ammeter $A$ are respectively
[2010]
(a) $150 V, 2.2 A$
(b) $220 V, 2.2 A$
(c) $220 V, 2.0 A$
(d) $100 V, 2.0 A$
Show Answer
Answer:
Correct Answer: 22. (b)
Solution:
- (b) As $V_L=V_C=300 V$, resonance will take place
$\therefore \quad V_R=220 V$
Current, $I=\frac{220}{100}=2.2 A$
$\therefore$ reading of $V_3=220 V$
and reading of $A=2.2 A$
