Inverse of Time is Frequency.
or

No.of cycles per second

Answer / natarajanramkumar

Frequency - It is defined as the number of cycles per
second.In india 50 c/s is common.
Frequency = NP/120
Where N is the speed in r.p.m.and P is no.poles of a
machine.

Answer / prasad

no of cycles per second

Answer / gourav buldev

it is nothing but the rotation of the turbine in electrical generation 50 Hz supply means that a generator turbine is taking rotation of 50 round per second this system is running in INDIA by following other countries too...

In some countries the speed of turbine is 60 cycles per second then they get 60Hz supply for their grid...

Thanks

Answer / santhoshkumar

No. Of cycles of the repititive
waveform per second

Answer / zain

Frequency is the time period for chane one cycle.it is used
in AC current.when one cycle at 90 degree thet will be +
or - in AC current the second cycle of another 90 degree
will be + or - which will complete first 90 degree to 360
degree.this time period to complete one cycle that is 0
degree to 360 degree is known as frequency.The frequency of
AC current in pakistan is 50/60 Hz.

what is the exact direction of current? as we know current travels from higher potential to lower potential,so if we take battery +ve to -ve implies current direction is from positive terminal to negative terminal.,whereas electrons flow from negative to positive as they are attracted by positive ions.current will be the plow of charge but not flow of positive ions.please clarify my doubt friends.
