Series LC resonant frequency, two ways

The same calculation run twice, side by side. Change anything on either side and the difference is shown output by output. This page is a link: both sets of numbers are in the address bar.

Side A open alone
mH

The total series inductance — in a VIC, the chokes in the charging path.

nF

The cell capacitance, water dielectric included.

Side B open alone
mH

The total series inductance — in a VIC, the chokes in the charging path.

nF

The cell capacitance, water dielectric included.

Swap sides

What changed

The two sides are the same. Change something on either.

Output A B B against A
f Resonant frequency 6.497 kHz 6.497 kHz same
ω Angular frequency 40.82 kHz 40.82 kHz same
Z Characteristic impedance 20.41 kΩ 20.41 kΩ same

Side A, with its numbers

6.497kHz=12π500mH·1.2nF
LaTeX
6.497\,\mathrm{kHz} = \frac{1}{2\pi\sqrt{500\,\mathrm{mH} \cdot 1.2\,\mathrm{nF}}}

Side B, with its numbers

6.497kHz=12π500mH·1.2nF
LaTeX
6.497\,\mathrm{kHz} = \frac{1}{2\pi\sqrt{500\,\mathrm{mH} \cdot 1.2\,\mathrm{nF}}}
