I am typing up all my old electronics assignments into notes and for the life of me I cannot figure out how I got the last 4 answers. I know T is RC, VC at 0s is always 0 and IC at zero is always the total current. Can anyone help me understand again how to do the last four questions.

 

Take a look at the AAC ebook on series RC circuits. You should be able to find your asnswer there.

Thanks for the reply ,but the link you sent me does not provide a formula for calculating exact current or voltage of a capacitor at a period in time.

 

You just needed to go go a bit further in the section to find out more. Here is the voltage versus time section.
