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
