What This Calculator Does

This calculator models a driven series RLC circuit at a selected frequency and reports the electrical quantities engineers usually inspect first: impedance, current, reactance balance, resonance, quality factor, and bandwidth.

It combines Resistance, Inductance, Capacitance, Source Voltage to estimate Impedance, Current, Phase Angle.

Formula & Method

Core equations: X_L=2pi fL,quad X_C= rac{1}{2pi fC},quad |Z|=sqrt{R^2+(X_L-X_C)^2},quad I= rac{V}{|Z|},quad f_0= rac{1}{2pisqrt{LC}}.

Notation used in the formulas: R = Impedance; x_{1} = Resistance; x_{2} = Inductance; x_{3} = Capacitance; x_{4} = Source Voltage; x_{5} = Frequency.

Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.

Use it when checking whether a chosen drive frequency is below, above, or near resonance, or when estimating current magnification and selectivity in a simple tuned series network.
