a) an electric current that reverses its direction many times a second at regular intervals, typically used in power supplies.

b) The frequency of Alternating Current in India is 50 Hz


c) The periodic time of an AC current in India is 1 by 50Hz per sec. the frequency of Alternating Current in India is 50 Hz. This simply means that the magnetic field around the armature in the AC Generators in India rotates 50 times per second


d) The major advantage that AC electricity has over DC electricity is that AC voltages can be readily transformed to higher or lower voltage levels, while it is difficult to do that with DC voltages. Since high voltages are more efficient for sending electricity great distances, AC electricity has an advantage over DC.


e) AC generators are cheaper to produce

The power they generate is easier to step up and down via transformers


Hope this helps you.
