Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I'm stuck on this charge equation:

Q=Q * e (-t/RC)

= 780 * e (-9.8/3.3)

I've got 40.03

but the answer is 15200

if I took away the negative sign from the equation then I'll be able to get 15200. but that should not be the way isn't it? can somebody advise me how should I go about with this?

thanks
