Capacitors, Inductors & Reactance
Every capacitors, inductors & reactance calculator on CalcEngines — unit converters, derived indices and interpretive tools, each with its formula, a worked example and the reference intervals it is judged against.
3 calculators in this section
- Capacitive and Inductive Reactance CalculatorReactance of a capacitor or an inductor at any frequency — X_C = 1/(2πfC), X_L = 2πfL — with the current it allows at a stated voltage, the 90° phase shift, and the net reactance when both are in series.
- LC Resonant Frequency CalculatorResonant frequency of an LC tank from the inductance and capacitance — or the capacitor you need for a frequency you already have — with the characteristic impedance, Q, bandwidth and the frequency band your component tolerances really allow.
- RC and RL Time Constant CalculatorThe time constant τ of a resistor-capacitor or resistor-inductor circuit, how far it has charged or discharged after each τ, the time to reach any percentage, and the voltage and current at any moment, with the charging curve drawn from 0 to 5τ.
