Okay. So I got the correct answer by finding the new Q and plugging it into that equation you gave me for the first part of the question. However, I still do not know where you derived that equation from. My class is strictly algebra-based and we have not even mentioned differentials yet.
ΔQ/I...
Yes, it has changed. I realize that, but what equation am I missing that relates all of these elements to time? In my notes from class, I recorded that, when something is discharging... V(t)=V(0)e(-t/t-constant)
Would I find a new initial voltage through Q=VC and plug it into that equation I...
If two of these capacitors are placed in a series, how long (in days) would it take? In parallel?
I can calculate the two equivalent resistances for this question, but are they even really needed?
Homework Statement
Compact "ultracapacitors" are with capacitance values up to several thousand farads are now commercially available. One application for ultracapacitors is in providing power for electrical circuits when other sources (such as a battery) are turned off.
