Answer Posted / daniel joel
DC is a constant source
generator and all our
electronic devices require a
constant supply to operate
suppose if we consider AC its
vaule change at every instant
of time. Normally all electronic
devices has specific vaule to
operate if it increases further
then the device may damage
so as DC is constant the
devices operate on it by
converting AC into DC by the
rectifiers.
