Why is current maximum when voltage is zero in an AC capacitor?

In AC circuit when the voltage is zero the current is maximum...
When it reaches to 90 then the current is zero...
And same as for the other cycles till 360...

Why the current is maximum when the voltage is zero and when the voltage is maximum the current is zero...?

Please explain...

 

[uart]

The current is proportional to the rate of change (derivative) of voltage.

can u explain it a bit more?

 

[uart]

$$i = c \frac{dv}{dt}$$Do you know what "rate of change" is?

A quick google search turned up this...

I think it explains it pretty well.

Yes.
