How to Calculate Voltage for a Capacitor Charged by a Constant Current?

kari7921 · Nov 22, 2010

1.
The question asks, to what voltage would a 60-microfarad capacitor be charged by a 6mA current lasting 10 seconds?

2.
I used this formula, V=1/C ∫i dt
but I'm not sure how to solve the integral.
Thanks for any help

Your integral looks good. You just need to integrate the current with respect to time and multiply by 1/C.

Note the problem does not state that the initial voltage across the capacitor is zero.

If I did this correctly, I got a very nice even number - VERY even.
