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.
