If you are interested in calculating the LC (Resonant) circuit, you are in the right place. You can use it for a variety of purposes such as designing a filter, analyzing an amplifier, etc. It is a very useful tool for engineers, scientists, and hobbyists.

You can choose the values for the various components such as the capacitance and the inductance. Once you enter the values, you will be able to calculate the resonant frequency of the circuit. You can save the results in a CSV (Excel) file so that you can read it later. You can also use a text editor to edit the values.
