This app is used to calculate LC resonant circuit. It is suitable for hobbyist or electronic engineers. Features: 1. Calculate resonant frequency by capacitor and inductor values 2. To find out combinations of capacitance and inductance making a desired resonant frequency 3. Save all combinations in a CSV (Excel) file 4. Use preferred values of capacitors and inductors Features in PRO version only: 1. selectable preferred value 2. No Ads 3. No limitation Note : 1. For those who need support please email to the designated email. Do NOT use either the feedback area to write questions, it is not appropriate and that is not guaranteed that can read them.
