Capacitors store energy in the form of an electric field; this mechanism results in an opposition to AC current known as capacitive reactance. For both series and parallel connection of the RLC circuits, resonance occurs at XL = XC when the source current is in-phase with the circuits supply voltage. Summary. Shes a research powerhouse and has numerous Then, youll discover how both AC and DC circuits are formed and how to calculate the power supplied through these circuits. Because DC circuits have no frequency and the amplitude of DC is constant, capacitive and inductive reactance in DC circuits is zero. In an AC induction motor, as slip increases from zero to ~10%, the torque increases linearly. What is Electrical Identification? The circuit diagram and the equation for the series RLC circuit are: I_S=\frac{V_s}{Z}=\frac{V_S}{\sqrt{R^{2}+(X_C-X_l)^{2}}}.
