ac changes its direction in every 1/100 second in India.so its frequency must be 100 hertz?

Question

ac changes its direction in every 1/100 second in India so its time period is 1/100.so frequency must be=1/time period=1/1/100=100 hertz.but the frequency of ac in India is 50 hertz how?

Answer 1

frequency is measured in hertz. which means cycles per second. yes it changes direction ecry 1/100th of a second but to complete one full cycle of the sine wave curve from start to finish takes twice as long so the frequency is 50 cycles per second.

Answer 2

The direction of ac changes every HALF period, so a full period is 1/50 sec in India

Answer 3

time period of ac is 1/50 therefore its frequency is 50 hertz

Answer 4

ac changes its direction in every1/100 seconds that in every 0.001 second ac changes its direction

so in the time 1 second ac changes its direction 50 times hence we say frequency is 50 hertz.

Answer 5

time period=2*(time taken to change dir'n)

frequency=1/time period

=1/(2/100)=50

Answer 6

No i think its 50Hz to 60Hz

because in India we get electricity of 220V to 240V

so 100Hz capacity wont be working in 240V :-? it needs more

if 440V is given to the AC i hope it will work :)
