Well, you gonna find all what you want inside the zip file. all classes of java, you just need to download as i explain in my last post.

dear Author,
I am a student and I want to ask about the method by which we can conclude a formula for calculating the current I as a function of time while discharging a capacitor ( in RC circuits of course ) because the method shown in my book gives a negative sign of a decreasing current and by using the opposite direction on the drawn circuit I get a positive "increasing" current.

Assume the charge in capacitor is q,  the current is defined as I=dq/dt
, then I=dq/dt> 0 while charging (I>0 means current flow into the capacitor),
and I=dq/dt<0 while discharging (I<0 means current flow out of capacitor).

If you defined I' mean current flow into the capacitor, then dq/dt=-I' while discharging (in this case: you got a negative sign of current I').
