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.

DC

Answer / prashant tiwari

NOT CORRECT.IT IS A STATIC CURRENT THAT CAN NOT EVEN MEASURE.

Answer / aniruddh

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.

Answer / k.prakashchandra

It is a discharge between oppositely charged

Answer / nagendra

stictly speaking it is unidirectional in nature

iii) A shunt motor runs at 70 rad/sec from a 460V supply and takes in an armature current of 100A. Resistors of 2.52 ohms and 1.64 ohms are connected in series with the armature and in parallel with the armature respectively. The field excitation remains direct from the 460V supply but the generated torque is halved. Determine the new running speed. Neglect brush voltage drop. The armature resistance is 0.4 ohms. [15]
