capacitor equation solution not working

I am trying to solve a very simple circuit, one that has only a capacitor in it. What am I doing wrong? The final graph should show that the capacitor has discharged, but its staying constant. I have current starting at t=10 and ending at t=60. I hope I have used the correct way to put in my code, I am using a new computer and I having trouble with my email program. Any advice would be appreciated. Thanks My code. I[t_]:= If[t<10||t>60,0,1] Plot[i[t],{t,0,100}] Eq=v'[t]==i[t]/c c=1; Soleq==v[t]/.NDSolve[{eq,v[0]==0},v[t],{t,0,100}],[[1]] Plot[soleq,{t,0,100}]
