Online Calculators since 2009
The Impedance Calculator will calculate the:
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 = √R2 + 2 × π × fd × L - 1/2 × π × fd × C2|
Z = √2 + 2 × × × - 1/2 × × × 2
Z = √ + - 1/2
Z = √ + - 2
Z = √ + 2
Z = √ +
Z = √
|Impedance Calculator Input Values|
|Driving frequency of the circuit (fd) 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.
This formula derives from
is the driving angular frequency in the RLC circuit.
The following Physics tutorials are provided within the Magnetism section of our Free Physics Tutorials. Each Magnetism tutorial includes detailed Magnetism formula and example of how to calculate and resolve specific Magnetism questions and problems. At the end of each Magnetism tutorial you will find Magnetism revision questions with a hidden answer that reveals when clicked. This allows you to learn about Magnetism and test your knowledge of Physics by answering the test questions on Magnetism.
