As per i know, As led consists of parasitic capacitance during the supply it gets charged and discharges the stored energy when supply is not there this causes led to glow for some time

As per i know, As led consists of parasitic capacitance during the supply it gets charged and discharges the stored energy when supply is not there this causes led to glow for some time Yes, one more thing.... Even if there is some leakage current is existing in the system LED glows beacuse the selected LED might not have low voltage glow protection. That means now a daysmanufacturer usedLEDs whichrequires a certain voltages to glow and hencenuisancecan be avioded.
