Regarding the LC series circuit, this article will explain the information below. Equation, magnitude, vector diagram, and impedance phase angle of LC series circuit impedance Impedance of the LC series circuit An LC series circuit (also known as an LC filter or LC network) is an electrical circuit consisting of an inductor \(L\) and a capacitor \(C\) connected in series, driven by a voltage source or current source. The impedance \({\dot{Z}}_L\) of the inductor \(L\) and the impedance \({\dot{Z}}_C\) of the capacitor \(C\) can be expressed by the following equations: \begin{eqnarray}{\dot{Z}}_L&=&jX_L=j{\omega}L\\\\{\dot{Z}}_C&=&-jX_C=-j\frac{1}{{\omega}C}=\frac{1}{j{\omega}C}\end{eqnarray} ,where \({\omega}\) is the angular frequency, which is equal ...
