Question

what would be the frequency of an alternating current if its direction changes after every 0.01 second​

Answer 1

Frequency is inverse of time

t = 0.01 sec

f = 1/t = 1/0.01 = 100 Hz

Answer 2

Answer:

100 Hz  - the frequency of an alternating current if its direction changes after every 0.01 second​

Explanation:

To answer this question we need to identify a formula connecting the time and frequency.  

The formula connecting time and frequency is given as follows :

F = 1/T

Where :

F = frequency in Hertz

T = Period in seconds

Given the time in seconds we can obtain the frequency.  

We substitute the given values in the formula above.  

Direction change after 0.01 means Total T = 0.02

F = 1/0.02 = 50 Hertz
