- Free online calculator for designing your own Tesla Resonant Transformer A.K.A. Tesla coil using Eric Dollard's equations. Available for desktop and mobile screen sizes.
- Calculate the increase or decrease in the strength of the magnetic field of a coil simply through changing the wire diameter with the free Ampere-Turn Calculator. Many more factors are also calculated for your convenience.
- The Coil Capacitance Calculator can be used to calculate the self-capacitance of air-cored single-layer solenoid coils. All you have to do is enter your coil length and diameter and it will take care of the rest. It also uses data interpolation to give you more accurate results.
- Calculate the inductance of your coil with ease. The Coil Inductance Calculator works with metric and imperial units, and is suitable for air-core single-layer solenoid, multi-layer solenoid and flat spiral coils.
- The Frequency-Wavelength Calculator will let you calculate either the frequency from the wavelength, or the wavelength from the frequency. Ideal for your radio frequency experiments and calculations.
- Enter your inductance and capacitance to calculate the resonant frequency. The Resonant Frequency Calculator is ideal for analysis and designing RF coils/inductors, circuits, oscillators and more.
- The LC Constant Calculator will calculate either the inductance or capacitance required in order to resonate a circuit at any frequency.
