why the current leads voltage in the case of a capasitor

Answer Posted / deepakindi1

current through capacitor=

ic= c dvc/dt

ie current through capacitor is a function of rate of
change of voltage applied across it, as applied voltage is
sinusoidal sine wave ,if u take a slope at zero croosing of
wave form rate of change of the voltage is maximum so is
the current at zero croosing of wave form is maximum. that
ic reaches its maximum before applied voltage that y
current through capacitor leads voltage

As we use capacitior bank in 3ph ckt for improvement of PF, why not we use capacitor in single phase domestric use, at our house their are many inductive equipments,like fan,mixer,tube choke,air conditioner they also draw PF... by using capacitor can they improve PF. if yes--what are advantage and how to connect a capactor in single ph,and which type of capacitor if no- what are disadvantages.
