First, select the desired RLC connection (parallel/series). Q is the quality factor of a parallel RLC circuit (dimensionless). The calculator defines the resonant frequency of the RLC circuit and you can enter this frequency or the value slightly above or below it to view what will happen with other calculated values at resonance. The Q factor, C and L reactance, and the resonant frequency will also be calculated. The calculator also defines the Q factor of the RLC circuit, a parameter, which is used to characterize resonance circuits and not only electrical but mechanical resonators as well. \( \theta = \arctan \left(\dfrac{R}{X_L}-\dfrac{R}{X_C} \right) \). In a parallel DC circuit, the voltage . The applied voltage remains the same across all components and the supply current gets divided. In the English language, a parallel RLC circuit is often called a tank circuit because it can store energy in the form of an electric field and a magnetic field with a circulating current like a tank can store liquid without releasing it.
