Question

What will be the frequency of AC if its direction changes after every 0.01 seconds ?

Answer 1

Frequency of alternating current after every 0.01 sec will be -:

Time period = 0.01×2(Since A.C. reverses two times)

Therefore, Time period =0.02 sec.

Frequency =1/time period.

Frequency =1/0.02

Frequency =50 hz

Answer 2

The frequency of AC will be 100 Hz.

• Frequency is the number of events of a rehashing occasion for every unit of time.
• It is likewise periodically alluded to as worldly frequency to underscore the differentiation to spatial frequency, and customary frequency to accentuate the difference to rakish frequency.
• Frequency is estimated in hertz which is equivalent to one every second.

                                       Frequency = 1 / time period

The given time period is 0.01 seconds.

Therefore,

Frequency = 1 / 0.01

Frequency = 100 Hz
