Homework Help: physics please!

Posted by kiksy on Wednesday, March 30, 2011 at 7:06am.

hi
im trying to do a problem that involves multiple battereis, one capacitor,and multiple resistors, and im told that the circuit has been connected for a very long time...
i found the current passing thru each battery using kirchoffs rules, but now i have to find the capacitor's stored charge---\i know i have to use the equation c=q/v

my question is: do i have to find an equivalent circuit to find v, or do i just use v of the nearest battery, or something else?? then , i have to find the energy lost in 1 minute, so would i use the same value for v for this part of the problem too?


please advise!!! thank you very very very very much
