Regarding the RLC series circuit, this article will explain the information below. Equation, magnitude, vector diagram, and impedance phase angle of RLC series circuit impedance Impedance of the RLC series circuit An RLC series circuit (also known as an RLC filter or RLC network) is an electrical circuit consisting of a resistor \(R\), an inductor \(L\), and a capacitor \(C\) connected in series, driven by a voltage source or current source. The impedance \({\dot{Z}}_R\) of the resistor \(R\), 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: ...
