An inductor of inductance (L) and a capacitor of capacitance (c) are connected in series. The net impedance of this circuit is
A) $$j \omega L + \frac { j } { \omega C }$$
B) $$j \omega L - \frac { j } { \omega C }$$
C) $$j \omega C - \frac { 1 } { j \omega L }$$
D) $$j \omega C + \frac { 1 } { j \omega L }$$

Quizplus · Accepted Answer

The net impedance of a series LC circuit is given by the sum of the inductive reactance ($j\omega L$) and the capacitive reactance ($-\frac{j}{\omega C}$). The correct formula is $j\omega L - \frac{j}{\omega C}$.
