Coil resonant frequency
calculator |
|
| |
|
| |
This calculates a coil's resonant frequency (f), inductance (L), and self capacitance (C), given its length and diameter as input. |
|
|
|
| |
|
| |
|
| |
|
|
|
| |
|
| |
This calculates the possible dimensions: lengths, diameters, etc.,
given the desired self resonant frequency (fr) of the coil as input.
Assuming that the coil will be a quarter wave oscillator ( λ = 4 ℓw). |

|
|
| |
|
| |
This calculates the possible dimensions: lengths, diameters, etc.,
given the desired self resonant frequency (fr) of the coil as input.
Assuming that the coil will be a half wave oscillator ( λ = 2 ℓw). |

Wire length spool calculator  |
|
| |
|
| |
This can be useful in obtaining the length of a wire on a spool.
Entering the weight of the wire on the spool in ounces, and the wire's gauge, this will calculate the length of the wire on the spool. |

Capacitance
calculator  |
|
| |
|
| |
Calculates the necessary capacitance (C) for a tank circuit at a given resonant frequency (f), and inductance (L). |

Primary coil turns
calculator  |
|
| |
|
| |
Calculates the possible number of turns of wire for a primary coil, with the given input of the coils mass, diameter of the coil, and the wire's gauge. |
