The Impedance Calculator will calculate the:

- The impedance of a RLC circuit when resistance, capacitance and inductance are given

**Calculation parameters:** The conducting wire of circuit and material the inductor is made from, are both uniform and they have the same thickness everywhere; the source supplies AC current.

The Impedance of the circuit is Ω [Ohm] |

Impedance of the circuit calculation |
---|

Z = √R^{2} + 2 × π × f_{d} × L - 1/2 × π × f_{d} × C^{2}Z = √ ^{2} + 2 × × × - 1/2 × × × ^{2}Z = √ + - 1/^{2}Z = √ + - ^{2}Z = √ + ^{2}Z = √ + Z = √ Z = |

Impedance Calculator Input Values |

Driving frequency of the circuit (f_{d}) Hz [Hertz] |

Resistance of the resistor (R) Ω [Ohm] |

Inductance of the inductor (L) H [Henry] |

Capacitance of the capacitor (C) F [Farad] |

Archimedes constant (π) |

Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each impedance calculation, the Impedance Calculator will automatically calculate the results and update the Physics formula elements with each element of the impedance calculation. You can then email or print this impedance calculation as required for later use.

We hope you found the Impedance Calculator useful with your Physics revision, if you did, we kindly request that you rate this Physics calculator and, if you have time, share to your favourite social network. This allows us to allocate future resource and keep these Physics calculators and educational material free for all to use across the globe. We believe everyone should have free access to Physics educational material, by sharing you help us reach all Physics students and those interested in Physics across the globe.

Z = √**R**^{2} + 2 × π × f_{d} × L - *1**/**2 × π × f*_{d} × C^{2}

This formula derives from

Z = √**R**^{2} + ω_{d} × L - *1**/**ω*_{d} × C^{2}

where

ω_{d} = 2 × π × f_{d}

is the driving angular frequency in the RLC circuit.
