lightning current is ac or dc..?????

Answer / shailesh tankni
I think it is ac having a very high frequency, as when a
lighting discharge is there it induces a voltage of high
frequency in the transmission line.
due to this effect many times the domestic appliances also
gets damaged.
and this is the reason why the protection devices use
filtering devices like inductance and capacitance which are
designed according to the frequency value and is used to
bypass these induced charge and earth them.

both ac and dc dc current decay down after some ac
cycle.{after two cycle of ac}........

Answer / nizam
Initially it is an AC with very high amplitude,but within 2-3nsec after 4 cycle mostly it follows dc nature.Harmonics concept comes into picture thereafter.
