Electro Magnetic Induction And Alternating Currents Question 138
In the circuit, neglecting source resistance, the voltmeter and ammeter reading will respectively be [KCET (Engg.) 2001]
Options:
A) 0V, 3A
B) 150V, 3A
C) 150V, 6A
D) 0V, 8A
Show Answer
Answer:
Correct Answer: D
Solution:
The voltage $ V_{L} $ and $ V_{C} $ are equal and opposite so voltmeter reading will be zero.
Also $ R=30\Omega ,X_{L}=X_{C}=25\Omega $
So $ i=\frac{V}{\sqrt{R^{2}+{{(X_{L}-X_{C})}^{2}}}}=\frac{240}{\sqrt{30^{2}+{{(X_{L}-X_{C})}^{2}}}}=\frac{240}{30}=8A $
