How do you calculate the amount of joules stored in a capacitor bank?
The 4th Doctor (author)  Sandisk1duo8 years ago
its a pretty simple formula

J=V2/2(F) remember its in farads ex. 100uf would be .0001f
so you just take the rated voltage square it, divide that by two, then multiply by the capacity in farads

but theres also a much much easier way

So you intended it to look like this? J=V2/2(F)
