By integrating the current over 1 second intervals, you can find the total charge transferred to/from the cap during that interval. You then use the relationship between charge, voltage and capacitance to determine the voltage at each step. in other words, the reference
The Fundamentals of Capacitors in AC Circuits
When an ac voltage is applied to a capacitor, it is continually being charged and discharged, and current flows in and out of the capacitor at a regular rate, dependent on the supply frequency. An AC ammeter connected in the circuit would indicate a current flowing through the capacitor, but the capacitor has an insulating dielectric …
