The L-C-R circuit shown below is driven by an ideal AC voltage source. At frequency 
, choose the correct statement.
A
The current through 
is zero.
is zero. B
The current through 
is infinite.
is infinite. C
The current through 
depends on the value of L and 
.
depends on the value of L and . D
The current through 
depends only on the value of 
and not 
and 
.
depends only on the value of and not and .
Text Solution
Verified by ExpertsThe correct answer is:
D
The AC circuit is shown in the figure,
As 
, which is resonant frequency
So, 
and are out of phase
So, 
Hence, the current depends only on the value of 
and not 
and 
.
