Answer:
Answer
Correct option is
A
has a very high impedance
In LC parallel resonant circuit, the impedance is given by
Z=
X
C
−X
L
(X
C
)(X
L
)
In LC parallel resonant circuit, at the resonant frequency we have,
X
C
=X
L
∴Z=∞
Also, For pure resistor, Z = R
Hence,
In LC parallel resonant circuit, the impedance is near to infinity or very high.
Option A is correct.
Since, the impedance(resistance) is maximum, the current is negligible or zero it circulates back and forth between components without involving the source.. Hence, option B, C and D are incorrect.
