in a series

L-C-R

circuit, when connected to an AC source? Which one of the following curves represents the variation of impedance (Z) with frequency f in a series L-C-R circuit,

Which one of the following curves represents the variation of impedance (Z) with frequency f in a series L-C-R circuit,

Options

Correct answer

C. The position vector of the center of mass → r cm of an asymmetric uniform bar of negligible area of cross-section as

Step-by-step solution

Impedance

(Z)

of a series

L-C-R

circuit is given as Which one of the following curves represents the variation of impedance (Z) with frequency f in a series L-C-R circuit,

=\sqrt{R^2+\left(\omega L-\frac{1}{\omega C}\right)^2}

X_L=X_C

, then from Eq. (i),

Z_{\min }=R

, and

f=f_0 \quad\left[f_0=\right.

resonance frequency

]

Hence, the variation of

Z

with frequency

f

in a series

L-C-R

circuit is given as Which one of the following curves represents the variation of impedance (Z) with frequency f in a series L-C-R circuit,
