Capacitance in AC Circuits

At 0 o the rate of change of the supply voltage is increasing in a positive direction resulting in a maximum charging current at that instant in time. As the applied voltage reaches its maximum peak value at 90 o for a very brief instant in time the supply voltage is neither increasing or decreasing so there is no current flowing through the circuit.

Understanding DC Circuit Capacitor Behavior

Doubling the supply voltage doubles the charging current, but the electric charge pushed into the capacitor is also doubled, so the charging time remains the same. Plotting the voltage values against time for any capacitor charging from a constant voltage results in an exponential curve increasing toward the applied voltage.
