Hi guys,

With reference to this site: http://www.nessengr.com/techdata/rescharge/rescharge.html

I'm trying to work out the time it takes for capacitor C2 to charge.

There is an equation for the voltage a C2 at time t. But I'm unsure how to rearrange this to t=...

Any help would be appreciated.

The resonant frequency for the charging waveform is f = ωo/2$\pi$.

The time for the capacitor to reach the first resonant peak voltage is 1/4 cycle or 1/4f.
