Q. Out of the following graphs, which graph shows the correct relation (graphical representation) for LC parallel resonant circuit ?Physics Question ImagePhysics Question Image

MHT CETMHT CET 2017Alternating Current

Solution:

At resonance $\omega=\frac{1}{\sqrt{ LC }}$
$f =\frac{1}{2 \pi \sqrt{ LC }}$
At resonance the impedance is maximum and frequency and current will be minimum .
