    Current and voltage in ac are sinusoidal functions so as we see that one complete cycle is of. 0 - 2pie in sine function similarly its of 2pie / omega in ac so half cycle will be pie/ omega. Or in technical terms The time taken for an AC Waveform to complete one full pattern from its positive half to its negative half and back to its zero baseline again is called a Cycle and one complete cycle contains both a positive half-cycle and a negative half-cycle.

    Limitations of Ohm’s law :

    1. Ohm’s law is valid for metal conductors, provided the temperature and other physical conditions remain constant.
    2. Ohm’s law is not applicable to gaseous conductors.
    3. Ohm’s law is also not applicable to semi-conductors such as Germanium and Silicon.

    Consider an electrostatic field line terminating at a point, say P. Enclose this point in a Gaussian surface. The field line is going into the surface and not coming out of it - there is net inward flux (considering the field directed towards P). According to Gauss theorem this means that the Gaussian surface must enclose a negative charge. This then means that the field line can terminate at P only when there is a negative charge at P. If there is no charge at P, the net flux through the Gaussian surface must be zero and the field line must emerge out of the surface. Thus an electrostatic field line can terminate only at a charge or it must continue to infinity.
