Question

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

Answer 1

As we know that frequency is the reciprocal of the time period

Therefore time= 0.01 s

Frequency = 1/ time i. e.

1/0.01=

100 Hz

Answer 2

To find out the frequency of an alternating current if its direction changes after every 0.01 seconds​, we would follow these steps:

Time taken to change direction= 0.01 seconds

Time taken to complete every cycle = 0.02 seconds

Number of cycles completed in 1 second = 1/0.02 = 50

Hence, the frequency of an alternating current is 50 Hz if it changes direction after every 0.01 seconds
