Electro Magnetic Induction And Alternating Currents Question 138

Question: In the circuit neglecting source resistance the voltmeter and ammeter reading will respectively, will 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 VL and VC are equal and opposite so voltmeter reading will be zero.

Also R=30Ω,XL=XC=25Ω

So i=VR2+(XLXC)2=VR=24030=8A
