- #6Which of the following plots may represent the reactance of a series LC combination?
FigureAns : (d)
The reactance of a series LC circuit is given by,
`` X={X}_{L}-{X}_{C}=\omega L-\frac{1}{\omega C}``
`` \Rightarrow X=2\,\mathrm{\,\pi \,}fL-\frac{1}{2\,\mathrm{\,\pi \,}fC}``
The correct relation between the reactance and f is represented by the graph in option
(d).
`` X=0``, when `` {X}_{L}={X}_{C}``.
Thus plot d represent the reactance of a series LC combination.
