Ic(t) = 10cos(1000t+pi/4) ,Vc(-0)=3 V, Cap = 1uf

Vc(t) = Vo + 1/C integralI(t) dt

ok so I took the integral of 10cos(1000t+pi/4) and got

1/100 sin (1000t+pi/4)

then I times ^ by 1/C which is 1000000.

The final result is vc(t)= 3+ 1000sin (1000t+pi/4)

Is this right? 1000 v seems unreasonable.
 

I think it should be 10,000 instead of 1000.
And i think it(10,000) is not possible in practical case .
 

10kV at 1uF is uncommon, but no big deal. This web site sells them to (daring) hobbyists:

1mfd 15Kv, 10 kilo amp, 6" X 6 x 4"
1/15KV - Low Inductance Capacitor..............$210.00
