Formula

Here are the formulas, the calculator uses to perform calculations,

Resonant Frequency Calculation Formula:

F = 1 / (2 * π * √(L * C))

Inductance Calculation Formula:

L = 1 / (4 * π^2 * F^2 * C)

Capacitance Calculation Formula:

C = 1 / (4 * π^2 * F^2 * L)

Where:

F is the frequency of the LC resonance circuit.

C is the capacitance of the capacitor in the LC circuit.

L is the inductance of the inductor in the LC circuit.

Example

Now, let's take examples to understand the actual calculation.

Resonant Frequency Calculation:

Suppose we have an LC resonance circuit with an inductor (L) having a value of 100 mH (millihenries) and a capacitor (C) with a value of 1 µF (microfarad). We want to find the resonant frequency (F) of this circuit.

First, convert the values to their base units:

L = 100 mH = 100 * 1e-3 H = 0.1 H (Henry)

C = 1 µF = 1 * 1e-6 F = 1e-6 F (Farad)

Now, calculate the resonant frequency (F),

F = 1 / (2 * π * √(0.1 * 1e-6))

F ≈ 503 Hz

So, the resonant frequency of this LC circuit with an inductance of 100 mH and a capacitance of 1 µF is approximately 503 Hz.

Inductance Calculation:

Suppose we have an LC resonance circuit with a resonant frequency (F) of 2 kHz and a capacitor (C) with a value of 10 nF (nanofarads). We want to find the inductance (L) of the inductor in this circuit.

First, convert the values to their base units,

F = 2 kHz = 2 * 1e3 Hz = 2000 Hz

C = 10 nF = 10 * 1e-9 F = 1e-8 F (Farad)

Now, calculate the inductance (L),

L = 1 / (4 * π^2 * (2000)^2 * 1e-8)

L ≈ 0.633 mH

So, the inductance of the inductor in this LC circuit with a resonant frequency of 2 kHz and a capacitance of 10 nF is approximately 0.633 millihenries (mH).

Capacitance Calculation:

Suppose we have an LC resonance circuit with a resonant frequency (F) of 1 MHz and an inductor (L) with a value of 500 µH (microhenries). We want to find the capacitance (C) of the capacitor in this circuit.

First, convert the values to their base units,

F = 1 MHz = 1 * 1e6 Hz = 1e6 Hz

L = 500 µH = 500 * 1e-6 H = 5e-4 H (Henry)

Now, calculate the capacitance (C),

C = 1 / (4 * π^2 * (1e6)^2 * 5e-4)

C ≈ 0.0507 nF

So, the capacitance of the capacitor in the LC circuit with a resonant frequency of 1 MHz and an inductance of 500 µH is approximately 0.0507 nanofarads (nF).
